  2. Shaders for the Sims themselves
  4. Most Sims shaders (currently) come from the Alias export.
  5. However, here are a few special ones.


  1. A gray default shader for when we can't find one

materialDefinition defaultSimsShader 

  setDefinition Phong
  addParam stdMatDiffCoef (.5, .5, .6)

end


  1. contains the shader pre-create commands for all Sim materials

define SimsShaderPreCreate() 

  preCreate -viewerRenderType $kRenderTypeNormal -viewerRenderType ($mirrorReflectionsEnabled ? $kRenderTypeMirror : $kRenderTypeNormal) -deformations
  1. < 
  preCreate -lights directional 2
  preCreate -lights directional 2 point 1
  preCreate -lights directional 2 point 2
  preCreate -lights directional 2 point 3
  preCreate -lights directional 2 point 4
  preCreate -lights directional 2 point 5
  preCreate -lights directional 2 point 6
  preCreate -lights directional 2 point 1 spot 1
  preCreate -lights directional 2 spot  1
  preCreate -lights directional 5 environmentCube 1
  1. >

  1. special layer for the censor shader. This ensures that the censor shader can
  2. be skipped during the censor render itself. The number is referred to from
  3. C++ code.

seti kCensorShaderLayer -1

  1. material to copy from the censor texture to the view target

define CensorCompositingMaterial()

  addParam      stdMatDiffCoef (1,1,1,1)

  2. Sims Shaders
  4. These include a version of the standard material
  5. (SimStandardMaterial) that is used for things
  6. such as hair and faces, and SimSkin, which is
  7. used for a body with composited textures.


  1. Any mesh subsets that use composited textures must be use the following material
  2. The aliasshader command tells the mel parser that SimSkin has the same parameters as StandardMaterial
  1. if compositing is to be used, these are the names of the composited textures

set compositeBaseTextureName "" set compositeBaseTextureParam "" set compositeSpecTextureName "" set compositeSpecTextureParam "" set compositeBumpTextureName "" set compositeBumpTextureParam ""

  1. allow at most 8 base (diffuse) textures to be composited

set baseTexture0 "" set baseTexture1 "" set baseTexture2 "" set baseTexture3 "" set baseTexture4 "" set baseTexture5 "" set baseTexture6 "" set baseTexture7 ""

  1. allow at most 8 specular mask textures to be composited

set specTexture0 "" set specTexture1 "" set specTexture2 "" set specTexture3 "" set specTexture4 "" set specTexture5 "" set specTexture6 "" set specTexture7 ""

  1. allow at most 8 normal map textures to be composited

set bumpTexture0 "" set bumpTexture1 "" set bumpTexture2 "" set bumpTexture3 "" set bumpTexture4 "" set bumpTexture5 "" set bumpTexture6 "" set bumpTexture7 ""

  1. the number of textures to composite

set numTexturesToComposite 0

  1. beginshader SimSkin
  2. description The basic material for defining a material that will be composited with Skin.
  3. extraparam int stdMatLayer 0 -32 32 ; attrdescription Layer for drawing, use even for opaque and odd for translucent
  4. extraparam enum stdMatAlphaBlendMode none (none)  ; Never blended
  5. endshader SimSkin
  1. generic overall hint (ie, in game)

setb useCPUCompositedTextures true

include DX9SimMaterials.matShad include DX8SimMaterials.matShad include DX7SimMaterials.matShad include SWVSSimMaterials.matShad

  1. face materials set this to 'true' so that the eyes can move.

setb eyeGizmoEnable false

  1. game will set this if in CAS, so all sim materials can composite on the fly.

setb simSkinFlag false setb contentViewer false


  1. This is a fudge factor, what this does is cover up a boo-boo I made.
  2. the lighting.txt file was 'tuned' using a DX7 sim material with a 0.4 multiplier, instead of 0.5 (x2 on the blender side to get back to 1.0)
  3. what this lead to was a desired look on dx7 cards, but dx8 and dx7 were washed out, being 20% brighter.
  4. so this fudge factor scales sims in dx8 and dx9 'down' by this amount to bring them into line with the "broken" dx7.
  5. for now, this is a temp fix for E3 2004, but this might live on forever.
  6. in a perfect world, this factor will be removed and the game lighting 're tuned' to use the unscaled lighting.
  7. this will probably need to happen anyway, with new materials and lighting models planned in the expansion packs.
