MetaShader

The MetaShader section of the SPDL file identifies the implementation of the shader for each of the renderers capable of using the shader.

This is an example of a multiple implementation shader. As of Softimage v4.0, it supersedes the Phenomenon section of the shader SPDL file.

MetaShader "water" 
{
   Name = "<shader-name>"
   Type = texture;
   Renderer "mental ray" 
   {
       Name = "water_mr";
       Options 
       {
          Scanline = off;
       }
   }
   Renderer "renderman" 
   {
       Name = "water_rm";

   BeginText
       color water_rm( )
       {
       return( noise( P ) );
       }
   EndText
   }

   Renderer "opengl" 
   {
       Name = "water_ogl";
       FileName = "opengl";
   }
}

Name

The name displayed in the Softimage user interface for the shader. The symbol name of the shader function is declared in the Renderer section.

Type

A comma-separated list of shader types that specifies the context in which the shader can be used. Softimage uses pre-defined types for mental ray and realtime shaders: lens, light, light photon, material, rtrendercontext, material photon, shadow, volume, volume photon, environment, output, geometry, texture and displace. Corresponds to the apply flag in a shader or phenomenon declaration in a .mi file.

The first type declared will define the preset family type, so if a shader has both the material and volume flags set, the preset will appear as a material preset in the file structure. However, the shader will still have the ability to be connected as a surface and volume shader to the material.

Realtime shaders use the type rtrendercontext.
