"The outline shader does whats on the tin. The cel-shader turns gradient shading into step based shading. They are typically both post process shaders."

I'll post other info if I get it, or contact info for people that are interested in discussing.

"I don't know the Godot particular workflow, but these trees are essentially a blob shaped mesh for the foliage which has a outline shader and a cel-shading shader applied."

Ah, and I'm following Seven Part Pact pretty closely now.
