Class 3: Slim, Part I

Introduction to Slim

Slim is the "shader UI" part of MTOR. It communicates with Maya to query certain lighting parameters, material attrs, etc. For the most part, shaders in Maya are ignored - equivalent RenderMan ones need to be set up via Slim.

Rich shader networks can be created using Slim..

Palettes, appearances, connections

Here's a small scene with a shader network.

Palettes can be renamed, stored on disk and read back

Here is how palette info. is stored in a Maya scene:
