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.
Location: This shader is still supported as a legacy shader, but has been removed from menus in Softimage. Scenes containing this shader
will display correctly. Load this shader into the render tree from Nodes

The Multiple Textures shader combines four Single Texture shaders OGL_Single_Texture in one property editor. You can set their basic attributes, and blend them using the modulation functions. However, the modulation functions offer very limited blending capabilities, so for full control over blending functions, it's best to use multiple Single Texture shaders, as oppose to a single Multiple Texture shader. The advantage of the multiple texture node is that it does multi texturing in a single pass.
