I'm working on writing a renderer plugin for 3ds max right now.
What I'm curious about is how I can choose what materials appear in the material editor when my renderer is selected.
For example:
When the default scanline renderer is selected, only materials in the "Standard" category appear in the material editor.
When mental ray is selected, a "Mental Ray" category appears in addition to "Standard"
When iray is selected, only a subset of the "Standard" materials are available.
Can anyone point me to some SDK documentation on this subject?
