SI_Material

Defines a SI|3D material.

 

In v3.0 only SI_Material is exported. In v3.5 and 3.6, SoftMaterial is exported as SI_Material, and regular Material is exported as XSI_Material.

This template corresponds to the CSLMaterial class.

Introduced

1.3

Limitations

Autodesk Softimage exports this template in v3.0. For v3.5/3.6, Softimage exports it when there is a legacy shader imported from SI|3D (via either dotXSI v3.0 or the ImportSi3D).

See XSI_Material for the corresponding Softimage template.

SI_Texture2D

Local 2d textures applied to the material. If not present, the face is untextured.

SI_ElementUserData _<userDataTag>

Material user data.

Note: This tag is only available in SI|3D.

Example (Lambert shaded material)

SI_Material myMaterial
{
   1.0; 0.0; 0.0; 0.0;;     // diffuse (red)
   1.0;                     // specular exponent
   0.0; 1.0; 0.0;;          // specular (green)
   0.0; 0.0; 0.0;;          // emissive color (black)
   1;                       // Lambert shading model
   0.3; 0.3; 0.3;;          // ambient color (light gray)
}
