Viewing Window

  • FaceGen Modeller uses OpenGL 1.1 graphics acceleration.
  • With the mouse positioned over the face, you have the following controls:
    • Rotate: left-click & drag.
    • Scale (camera field of view): right-click & drag up / down.
    • Scale (camera distance): shift-right-click & drag up / down.
    • Translate: shift-left-click & drag.
    • Symmetric Freeform Deformation: ctrl-left-click & drag.
    • Asymmetric Freeform Deformation: ctrl-right-click & drag.
    • Move Light Source 1: left-AND-right-click & drag.
    • Tip: When using the freeform deformation controls, FaceGen 'guesses' the most likely facial deformation you are trying to achieve. If it doesn't guess right, try moving slightly different points in slightly different directions. Also remember that your control is only 2-dimensional. You are only moving points in the plane perpendicular to your line of sight.
    • Tip: The freeform deformation tool will give you finer shape control when you have a high-resolution mesh selected, and coarser shape control when you have a low-resolution mesh selected.
  • You can increase the size of the viewport by position the mouse over its border and dragging the border. Note that you may have to increase the size of the entire Modeller window first, in order to make room for the viewport to expand.
  • Detail Texture
    • Adds small-scale detail to the statistically reconstructed texture.
    • This can be useful since statistically reconstructed skin textures tend to be very smooth.
    • Some detail textures do not look correct with all faces (for example, beard stubble detail doesn't look good on female faces). Reset the detail texture to 'None' to remove it.
    • Visual catalog of the detail textures included with Modeller 3.1 for each different racial group:
    • If you load a FaceGen file created with the PhotoFit, you will get a 'Photo Detail' detail texture. This contains details from the photograph which are not reconstructed by the FaceGen statistics.
    • You can create your own detail textures and add them to FaceGen:
      • Download and unzip the mean internal texture image.
      • Make copy of the image and modify the copy to add the detail you want. Do not change the size of the image, the layout of the features or the color of the image (skin color can be changed later, in Modeller). Save the result as a BMP.
      • Note that detail is only used in the face region - the region from mid-forehead to the top of the neck, in front of the ears. Any detail you do outside of that region WILL BE IGNORED.
      • Download and unzip the extractDetailTexture.exe utility. From the DOS command line, type 'extractDetailTexture -i meanTexture.bmp copy.bmp myDetail.jpg'.
      • Copy the file 'myDetail.jpg' (or whatever you have named it) into the 'Detail' sub-directory of your FaceGen directory (usually C:\Program Files\Singular Inversions\FaceGen Modeller 3.1\).
      • When you re-start FaceGen Modeller, it will appear in the Detail Texture drop-down menu.
    • You can also edit detail textures already in FaceGen:
      • You can directly edit any of the detail textures in the 'Detail' subdirectory of your FaceGen directory (we recommend working with a renamed copy of the file).
      • To edit a 'Photo Detail' from an FG file, use the the extractDetailTexture.exe utility. From the command line, type 'extractDetailTexture -f myFgFile.fg detail.jpg'.
      • Detail textures are modulation maps; pixels (R, G and B components) with a value of 64 will remain unchanged from the statistical texture created in FaceGen, those with higher values will be amplified, and those with lower values will be reduced.
      • To remove parts of a detail texture, just paint over with the color (64,64,64).
      • Re-start FaceGen Modeller to see your changes.
  • Detail Texture Modulation
    • Allows you to increase or decrease the amount of the current detail texture in the face.
    • Useful for reducing the detail in light colored faces where the detail texture is too harsh, or increasing it in darker faces where the detail texture does not have enough contrast.
  • Texture Overlay
    • Allows you to composite images over the FaceGen skin texture.
    • The default model set includes an example overlay for short black hair.
    • You can create your own overlay textures for things like hair, tattoos or shading.
    • The compositing approach differs from FaceGen detail textures (discussed above) in that:
      1. It is not limited to the face area.
      2. It is model specific.
      3. It works by compositing, not modulation.
    • To create your own overlay textures:
      1. Locate the root filename of the mesh you want to modify. It will be in one of the 'csamXXX' directories in your FaceGen directory (usually C:\Program Files\Singular Inversions\FaceGen Modeller 3.1\). You can see which root filename corresponds to which model part name by looking at the '<root>.fr3d' files in that directory with a text editor.
      2. Use the mean texture of this mesh, <root>.bmp as a guide for creating your composite texture
      3. Save the RGB component of your composite texture as a JPEG to the filename <root>_ovi_<compositeName>.jpg in the same directory.
      4. Save the alpha (transparency) component of your composite texture as a JPEG to the filename <root>_ova_<compositeName>.jpg in the same directory.
      5. When you re-start Modeller, your new overlay should appear in the Texture Overlay drop-down list on the bottom left whenever that model part is loaded.
      6. You can combine as many overlays as you want. Remember that the order in which you overlay can make a difference. You can re-order your overlays as you wish.
  • Texture Gamma Correction
    • Changes the gamma correction of the FaceGen statistical face texture images. It will not affect non-statistical (non-face) texture images or custom textures.
    • CRT screens suppress the middle of the brightness range. Correcting color brightness values for this suppression is called gamma correction. Most screens have a gamma around 2.2.
    • When you export your models, the current gamma setting will be used to export the textures.
  • Change Polys
    • A shortcut for the menu command 'Model' -> 'Change Model Parts'.

    Generate Tab

    • Racial Origin Sub-Tabs
      • The racial origin group sub-tab effects all controls that tab except Gender, Age and Asymmetry.
      • The racial origin groups are broad groupings which inevitably have some amount of overlap.
    • Generate Button
      • Randomly generates a face from the current racial origin group.
      • If all the 'rand lock' selections are off (the default) the faces will be generated completely randomly.
      • Those controls that have 'rand lock' set will constrain the randomly generated face to the value of that control.
    • Set Average Button
      • Reset the face to the average face for the current racial origin group, using the current gender and age values.
      • Note that this will result in caricature and asymmetry having value 0.
      • The average 'All Races' individual is an equal blend of each of the four other racial origin groups.
    • S/T Controls
      • Sync Lock
        • The S/T Controls are divided into shape and texture sliders.
        • Shape sliders affect only the underlying geometry.
        • Texture sliders affect only the underlying color (texture map).
        • It is sometimes convenient to adjust these synchronously, which can be achieved using the 'sync lock' check-box.
        • Note that controls in other areas of FaceGen Modeller may affect shape and texture differently, changing the relative positions of the S/T Controls even though the 'sync lock' check-box remains on.
        • To return sync locked controls to the same relative position, uncheck the sync lock, move one control level with the other, and re-check sync lock.
      • Rand Lock
        • If you wish to fix the value of any of the S/T controls while generating random faces, turn on the Rand Lock for that control.
      • Gender
        • Male faces really are darker than female faces on average, however this may be exaggerated by FaceGen due to imperfections in our dataset.
        • Since color statistics do not extrapolate well beyond the normal range, if you are exaggerating gender values, you should unlock sync and exaggerate the shape more than the color (texture).
        • This control is independent of the current racial origin group.
      • Age
        • This control is independent of the current racial origin group.
        • FaceGen does not currently model young children.
      • Caricature
        • Caricature measures how different a face is from the average face of the same gender, age and racial origin group.
        • Most real people will have a caricature value close to 'Typical'.
      • Asymmetry
        • Most real faces have a perceptible amount of asymmetry - a value close to 'Typical' on our asymmetry scale.
        • Adding some asymmetry to your faces is important in order to make them look truly alive. Perfectly symmetric faces aren't as believable.
        • This control is independent of the current racial origin group.
    • Race Morphing Controls
      • There are as many ways to morph between racial origin groups as there are pairs of racial origin groups.
      • Each control shows how the current face compares to the difference between the averages of each of its racial origin groups.
      • This comparison combines shape and color (texture) differences.
      • In most cases, you will want to select the racial origin tab that best characterizes the current face before applying race morphing.

    View Tab

    • Diffuse Shading Mode
      • Gouraud. Diffuse lighting is calculated at each vertex and linearly interpolated over the facets, making the surface look smoothly curved.
      • Phong. Diffuse lighting is calculated at each pixel. This will generally make low poly models look a bit better than using Gouraud, however it is slower (an extra render pass) and can cause artifacts on highly foreshortened surfaces if you aren't using 4x FSAA anti-aliasing (see tips).
      • Flat. Each facet is considered flat and has the same lighting over its surface. This allows for easy viewing of the underlying polygonal surface.
      • Note that specular highlights are always Phong shaded in Modeller, regardless of this setting.
    • Texture Mode
      • With texture 'Off', you can see the underlying geometry by itself - no coloring. Better for examining shape.
    • Wireframe
      • Overlay the models with a wireframe of the mesh.
    • Shiny
      • Turns the specular component of your lighting up to 11 (in the Spinal Tap sense). Easier to see shape detail while still seeing color.
      • Specular highlights are always Phong shaded in Modeller.
    • Object Rotation
      • Pan / Tilt. Easy to control, but you can't make the face rotate around your line of sight.
      • 3 DOF Harder to control but you can put the face in any desired pose. To rotate the face around the view axis, move the cursor in circles.
    • Background Color
      • Change the view window background color. To restore it to the original black, use 0 for R, G and B.
    • Background Photo Mode
      • Once you have loaded a photo for comparison (see below) you can choose to have the photo appear transparent on top of the face (overlay) or have the face appear transparent on top of the photo (underlay).
    • Background Photo
      • Load Photo To compare your face with a photograph, use this button to load the photo image. It must be stored as a BMP, JPG, TGA or TIF.
      • Transparency Adjust the transparency of the photo or face, depending on the current background photo mode.
      • To translate the photo in the view window, ctrl-shift-left-click and drag in the view window.
      • To scale the photo in the view window, ctrl-shift-right-click and drag up/down in the view window.
    • Lighting Options
      • Lighting options will be remembered when you quit and restart Modeller, and are useful for matching the rendering properties of your game engine.
      • Ambient Brightness
        • The ambient component illuminates all surfaces equally, regardless of position or direction faced.
      • Light Source
        • Adjust the brightness of the light, and its incoming direction.
      • PreSets
        1. 60% Single frontal light, 40% ambient.
        2. 60% Off-centre frontal light, 40% ambient.
        3. 60% from 3 lights (front and each side, all elevated), 40% ambient.
      • Tip: To modify the shininess of a surface, edit the corresponding text files ending in the suffix '.fr3d' found in the directory 'csamDefault' in your FaceGen directory.

    Camera Tab

    • Projection Mode
      • A perspective view is how we normally see a face - from a relatively close vantage point. Orthographic projection allows you to view the face as if through a telescope from a large distance.
    • Perspective Controls
      • FOV Angle. Adjust the angle of the camera field of view, in degrees. You can also right-click-drag the mouse in the viewport.
      • Distance Ratio. Adjust the distance of the camera from the current model centre as a ratio to the largest dimension of its bounding box. You can also shift-right-click-drag the mouse in the viewport.
    • Orthographic Controls
      • Relative Scale. Adjust the size of the current object bounding box relative to the view window.
    • Reset Camera
      • To allow precise comparisons, the bounding box is not recalculated after you add or remove model parts. This can sometimes cause parts of the model to be sheared off. If this happends, just hit the Reset Camera button.

    Shape and Texture Tabs

    • Symmetry Sub-Tabs
      • The shape statistics are divided into symmetric and asymmetric components.
    • Labelled Controls
      • There are 56 symmetric shape, 26 asymmetric shape and 33 texture controls.
      • Each control ranges between plus and minus 10 standard deviations of the distribution.
      • Note that although 10 standard deviations by itself is very unlikely, one slider at 10 standard deviations out of many sliders is more probable. In other words, moving just one slider to an extreme value may not produce a totally unrealistic face.
      • The controls are not completely independent of each other; adjusting one slider will usually affect several others. This is how the FaceGen preserves the statistical validity of the face.
      • Note that sometimes the distribution of a control is not normal (bell-curved). For instance, when moving the symmetric texture control 'Eyebrows (whole) - Light / dark', you get unrealistic results more quickly on the light side than the dark side. In this case the distribution is skewed.
    • Set to Zero Button
      • Set all controls in the current view to 0
    • Mirror Button
      • (Asymmetric views only) Create the mirror image of the current asymmetry.

    Genetic Tab

    • Generate. The genetic interface is a good way to fine-tune a face to get a specific, intangible 'look' that you can't find a slider for. Just generate variants of the current face until you find one that looks more like what you want, and click on it. Repeat until finished.
    • Randomness. You can adjust how different from the current faces you want the random variations to be.
    • Tip: Since the genetic array has small windows, you should maximize the size of the face in the view window to be able to see subtle face differences in the genetic array windows.

    Tween Tab

    • Load Target Button
      • The first step is always to load a target face. Now you can morph between the current face and the target face, to an in-between face, hence 'tweening'.
    • Tween Controls
      • You can separately tween symmetric shape, asymmetric shape and texture.
      • This can be an effective way of copying a shape you like without changing the texture, or vice versa.
      • You can also exaggerate the differences between the current and target faces by moving the slider past them.

    Morphs Tab

    • These controls affect shape only - not color (texture). Unlike the controls in the 'Shape' tab, these controls are MESH SPECIFIC.
    • They are scaled from 0 to 1, where 1 is the morph target.
    • They are divided into four types:
      • Expressions should generally only be used one or two at a time.
      • Phonemes should generally only be used one or two at a time.
      • Modifiers can be used in combination with expressions and phonemes.
      • Morphs are anything else - elf ears and an elf nose for example.
    • These controls were created by an animation specialist and thus have a more traditional look than FaceGen's statistically created 'Shape' tab controls.

    PhotoFit Tab

    • Create a FaceGen face from one or more photos.
    • A frontal image is required. Left and right profile images are optional
    • Photo Guidelines
      • The most important step is to take good photos. To ensure good results, you must follow these guidelines:
      • Essential:
        • Faces must have the mouth closed and be in the neutral (relaxed) expression.
        • Eyes must be open and looking straight ahead.
        • Faces must be about 12 years of age or older.
        • The entire face must be in the photo.
        • Flash lighting must be used, and the face must not be otherwise brightly lit.
        • Images must be in color.
      • Recommended:
        • Glasses should be removed.
        • Hair should not cover the forehead or any part of the face.
        • The camera should be at least 3 feet away from the face.
        • The face should be at least 500 pixels high in the image.
        • In the frontal shot, your chin should slightly elevated as if you're looking just above the camera.
        • Focus your eyes on something just above the camera, rather than into the distance, to avoid a spacey look.
      • OK:
        • Facial hair is OK.
        • Flashes on both sides of the camera can be used.
        • Flash diffusers can be used.
      • Bad:
        • The face should not be painted (makeup is OK).
        • Avoid taking photos outdoors in daylight.
        • Drawings of faces may not yield good results.
      • Save your photos in the JPEG (JPG), BMP, TIFF (TIF) or TGA file formats.
    • Point placement
      • Left-click between points and drag to move them all.
      • Left-click on a point and drag to move it separately.
      • Right-click and drag to scale the size of the point layout.
      • The eye points should be in the centre of the eyes.
      • The outer cheekbone points should be inside of any sideburn hair. Don't worry if the crosshairs fall outside the zoomed placement window - you can adjust them by hitting the 'Back' button.
      • The nose flap points should be on the outermost edges of the nose flaps.
      • The mouth corner points ... well you get the idea.
      • The outer jaw points should be horizontally in line with the mouth corner points. It does NOT matter where the neck profile intersects the face profile.
      • The chin point should be at the bottom centre of the chin.
    • Choosing to preserve facial hair will add the facial hair to the detail texture. This will allow the facial hair to appear on the texture map of the final face, but it may not look appropriate after you adjust controls for, say, a more female face.
    • You can choose to use detail texture from the profile view as well if you have both profile images. For good results, make sure your profile images don't have specular reflections on the skin.
    • Before running the PhotoFit, to prevent possible errors, disable your screensaver and if you have user-selected anti-aliasing on your 3D graphics card, disable it as well.
    • Save the result to an FG file before proceeding - loading that FG file in the future will give you the identical result to repeating that particular PhotoFit.
    • Note that the gamma value (darkness and colour saturation) of the reconstructed face texture may differ somewhat from photo. If you wish to preserve the exact look of the photo, you can adjust the 'Texture Gamma Correction' slider on the lower left to better match the photograph.

    • File
      • New
        • Resets all controls to an all-races average female of age 30.
      • Open
        • Open a face in the FaceGen FG file format (.fg). The face is applied to whichever meshes are currently loaded (see 'Model' menu item). Several example FG files are provided with the download.
        • Modeller 3.1 will open FG files created with Modeller 2.2, 2.1, 2.0 or 3.0.
      • Save
        • Save a face in the FaceGen file format (.fg).
        • It does not matter what meshes are loaded (see 'Model' menu item) when the face is saved.
        • It is important to save your faces to the FaceGen format so you can apply them to different head meshes and accessory models at a later time (see the 'Model' menu below).
        • This option is only available to licensed users.
      • Export
        • Export your face model to 3DS, LWO/LWS, MA, OBJ/MTL, VRML1, VRML97 or XSI.
          • 3DS Max Users: Note that the 3DS file format breaks all quads into tris and duplicates vertices which map to more than one UV point. We recommend using the OBJ format.
          • Lightwave Users: Note that endomorphs appear automatically in lightwave if you read in the LWS (Lightwave scene) file generated by FaceGen instead of the LWO (Lightwave object) file (assuming you chose to export the animation morph targets).
        • Only the meshes currently being viewed (see 'Model' menu item) will be exported.
        • All texture maps will be exported to sequentially named BMP, JPEG, TGA or TIFF files (a dialog box lets you choose).
        • The exported geometry includes texture coordinates but not vertex normals (except XSI which must include normals). The vertex normals used within FaceGen are calculated simply as the average of the adjacent facet normals. Your software may use a slightly different algorithm. Note that fixed values cannot be used for different faces since the shape can vary widely.
        • Exported texture maps have currently selected gamma correction built into them.
        • Some accessory models (hair and teeth) make use of a transparency (alpha) channel in their texture image. Only the TGA and TIFF image file formats fully support this. Be sure to export your textures to TGA or TIFF if you want to preserve the transparency maps. Modeller adds alpha information to BMP image files, but most applications do not support that feature. Unfortunately, Photoshop can't even read BMP files with alpha information. We recommend using Paint Shop Pro.
        • Export is only available to licensed users. For evaluation purposes, you can download some exported models to ensure compatibility with your workflow.
      • Save Image
        • Saves the current face image to either a BMP, JPEG, TGA or TIFF image file.

          • We also offer an alternative model set (the Aqua model) on our downloads page.
        • Change Model Parts
          • Gives you a dialog box allowing you to load and unload any of the parts within this model set.
          • The model set that ships with FaceGen Modeller 3.1 includes high-resolution, medium-resolution and low-resolution meshes of the face and eyes, and low-resolution teeth.
          • These models are considered a set since they were constructed to fit together, in the same coordinate system.
        • Custom Texture
          • Allows you to replace the texture map for any of the model parts with one of your own.
          • Note that when you are using a custom texture, FaceGen controls will have no effect on the texture of that model part.

      Tips & Tricks

      • Getting Rid of the Jaggies
        • If you have a decent 3D graphics card you can adjust your rendering settings to greatly improve the look of the face by telling your system to use FSAA 4x, sometimes known as oversampling:
          1. Right click on the background and select 'Properties'.
          2. In the 'Display Properties' window, select the 'Settings' tab and click on the 'Advanced' button in the bottom right.
          3. NVIDIA users select the 'GeForce' tab and enable manual FSAA 4x.
          4. Radeon users select the 'OpenGL' tab, then choose the 'SMOOTHVISION' button then select 'anti-alias' 4x.
          5. For cards based on other graphics chips, play around ... let us know what you find.
          6. Restart Modeller.
        • Note that this setting will cause the PhotoFit to slow down dramatically and sometimes produce errors.
      • Creating Attractive Faces.
        • Everyone has personal preferences, but on average, the most attractive faces are those that are close to the average.
        • Psychologists have found that the most attractive female faces are those which look like the average 17 year-old female, in which the degree of femininity is exaggerated by about 25%.
        • To achieve this in FaceGen Modeller, select the race you want, slide the age to 17, move the gender just past 'female' and bring the caricature values as close to average as you think necessary.
        • The most attractive male faces are those which look like the average 25 year-old male, but with a slight amount (5%) of femininity !
        • Attractive faces are also more symmetric, so reduce the amount of asymmetry - but leave a little to keep the face looking real.
      • Creating Children From Two Parents
        1. Create the father's face (if it isn't already saved) and save it to an FG file.
        2. Create the mother's face or load it from an FG file.
        3. Select the tween tab.
        4. Select the 'Load Target' button and load the father's FG file.
        5. Move both sets of sliders half-way between the two.
        6. Adjust the gender and age sliders as desired.
        7. For young ages, reduce the detail texture modulation using the slider on the lower left.
      • Making Your Own Detail Textures.
        • See the discussion under the 'Detail Textures' sub-section of the Viewing Window section.
      • Changing The Look of All Your Faces
        • You can change the look of all your faces, for instance to change the average skin colouring or shading details, by modifying the average face texture(s) of your mesh.
        • This approach differs from FaceGen detail textures and overlay textures (discussed above) in that:
          1. It works by differencing, not modulation or compositing.
        • It is similar to overlay textures in that:
          1. It is not limited to the face area.
          2. It is model specific.
        • To modify the average face texture of your mesh:
          1. Locate the root filename of the mesh you want to modify. It will be in one of the 'csamXXX' directories in your FaceGen directory (usually C:\Program Files\Singular Inversions\FaceGen Modeller 3.1\). You can see which root filename corresponds to which model part name by looking at the '<root>.fr3d' files in that directory with a text editor.
          2. Make a backup copy of the original mean texture (<root>.bmp) or make a copy of the entire model part (<root>.*).
          3. Now modify the mean texture as desired but do NOT change the UV layout. You can also choose to double the size of the image one or more times, but do not change the aspect ratio or increase the size by any value other than a power of 2.
          4. When you re-start Modeller, all your faces will share this modification when you have the affected model parts loaded.
      • Modifying Hair Textures (or any other transparent texture):
        • The short black hair model texture in the default model set, and any other transparent textures you create with the Customizer, are saved using an alpha-channel BMP. Unfortunately, most image manipulation programs (such as Photoshop) cannot read this type of BMP.
        • For simple image editing tasks, we recommend using Axialis Icon Workshop, which can read and save alpha-channel BMPs.
        • If you prefer to work with another image editing program, then do the following:
          1. Export the hair model (preferably by itself by removing all other model parts using the 'change polys' button), and choose TGA as the exported image format.
          2. Modify the TGA (which has an alpha channel that any image manipulation program can read). Ensure the pixel dimensions remain a power of 2.
          3. In Modeller, from the 'Model' menu, choose 'Custom Texture' and substitute your new TGA for the hair texture.
          4. If you'd like your new texture image to become the default for that model part, use a program capable of creating alpha-channel BMP files to convert your TGA back into a BMP, then replace the BMP corresponding to the model part you are editing, in its CSAM directory (csam) within the FaceGen Modeller directory.


      • I installed successfully but when I try to run the program the screen just flashes and nothing happens.
        • Check that your display is set to "True Color" (24 or 32 bit) mode. Some systems will not render in "High Color" (16 bit) mode.
          • Select 'Display' from the 'Control Panel' (in 'Start Menu' -> 'Settings') and choose the 'Settings' tab.
          • Re-start FaceGen Modeller.
      • I installed successfully but when I try to run the program I get the message "this program has performed an illegal operation and will be closed down"
        • Your video card's OpenGL driver is likely the problem. You can try upgrading it, or you can bypass it altogether using the instructions below:
          1. Shut down FaceGen Modeller and any other programs that might use 3D graphics.
          2. Right click on the desktop and select 'Properties'.
          3. In the 'Display Properties' dialog box, select the 'Settings' tab. After 'Display:', note the make and model of video card (not monitor).
          4. Hit the 'Advanced' button.
          5. In the new dialog box, select the tab corresponding to your video card model. You should be able to find the filename of it's 'OpenGL Installable Client Driver'. The filename will end in '.dll'. Remember this name.
          6. Cancel out of the dialog boxes and start windows explorer.
          7. Go the 'system32' directory in your Windows directory ('\WINDOWS' or '\WINNT') and find the file of the same name. Rename it by adding an underscore to the beginning and end, such as '_name.dll_'.
          8. Restart FaceGen Modeller. Note that it will run more slowly because it will switch to default Windows software OpenGL drivers.
      • The color texture on the face looks strange or checkered
        • Check that your display is set to "True Color" (24 or 32 bit) mode. Some systems will not render properly in "High Color" (16 bit) mode.
          • Select 'Display' from the 'Control Panel' (in 'Start Menu' -> 'Settings') and choose the 'Settings' tab.
          • Re-start FaceGen Modeller.
      • The PhotoFit says I have 'Incorrect placement of markers'
        • Ensure the points are placed on the face as demonstrated in the smaller photo on the right.
        • If your photograph is rotated the points may be interpreted incorrectly. In this case, rotate the image so that the face is upright (the PhotoFit will do 90 degree rotations for you but smaller rotations require the use of an image editing program) and try again.
        • This message can also happen for extremely unusual faces, or drawings of faces. In this case, make a compromise between the intial 'average' point positions and the positions for your extreme face.
      • The PhotoFit gives me an error
        • Check that you are running the latest release of Modeller 3.1:
          • From the 'Help' menu, select 'About FaceGen'.
          • Ensure that the version is '3.1.4', not '3.1'.
          • If you are not running the latest release, re-download the demo. Uninstall your existing copy and reboot before installing the updated version.
        • Make sure you try running the PhotoFit with no other 3D programs running, and do NOT obscure the PhotoFit window.
        • Disable your screen saver so that it does not obscure the PhotoFit window while the PhotoFit is running.
        • Check that you have installed the most recent OpenGL drivers for your graphics hardware.
        • If it still won't work, try a different computer with a different graphics card.
      • The PhotoFit runs extremely slowly
        • Ensure you have OpenGL drivers installed for your graphics hardware.
          • FaceGen warns you on startup if you do not (although this warning can be turned off after the first time).
          • Install the latest version of the drivers for your graphics card.
        • Ensure that OpenGL anti-aliasing is turned off in your graphics driver options.
          • Just reverse the instructions above under 'Getting Rid of the Jaggies' in the Tips & Tricks section.
      • The exported hair texture doesn't look right in my rendering application
        • Make sure you export the textures to TGA or TIFF formats in order to preserve the transparency information (it's not preserved in JPG or BMP).
        • If you're still having problems in Lightwave:
          • Extract the alpha channel info and save it as a separate grey scale map.
          • In the surface editor use this as a transparency map for the hair texture.
          • Note that you have to invert the grey scale map since in Lightwave black is opaque and white is transparent.
