DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage shader library.
This shader is designed to author content for DirectX. It is used to render shadows on one or more shadow receiving objects. It is meant to be used with the DXShadowMap shader, which should be applied to the shadow casting object.
