Hi I'm running into a problem where I am using a cutting plane to simulate material passing through an object. The moment the cutting plane is active per-pixel lighting is selectable and is on, but renders no effect in the viewport.
Here is an example:
Cutting plane visible (no per-pixel lighting effect visible):
Cutting plane hidden (per-pixel lighting effect visible):
Is there a way to allow both per-pixel lighting and a cutting plane to be both active and visible at the same time?
