Here is my experiment shader on how to create rim light without light in a way to optimize the render and the process for the compositing step.
It can be very useful to create rimlight pass.
You can create different rim : left, right, top, bottom, back, front and setting different thing like rotation, spread, smooth, fg contribution ...
The shader work with the vector of the mesh and follow the camera movement.

You can download it here : link

DepthRGB_V1.js
This tools allow you to generate a depthRGB Pass.

Two null (as depth controller) and a custom property are created inside the camera.

The color of the depth can be modified directly in the shader build by the script.

The script can be download here

some experiment around the Diffusion Limited Aggregation process in softimage ice:

Experiment done with softimage ice without lagoa

Work with animated and textured mesh
