Detailed Description

There are four channels which are part of the Material which are not specific to the Shader.

All other channels are defined by the Shader (what they are and what they are called). The four which are not the province of the Shader are Bump, Reflection, Refraction and Displacement. For example, Displacement mapping is really a geometry operation and not a shading one. The channel type returned from this method indicates if the specified channel is one of these, or if it is a monochrome channel, a color channel, or is not a supported channel.

Indicates that the channel is not supported.

For example, a certain Shader might not support displacement mapping for some reason. If it didn't, it could use this channel type to eliminate the support of displacement mapping for itself. It would be as if displacement mapping was not included in the material. None of the 3ds Max shaders use this.
