I noticed that the documentation now has the 3.0 shader language: http://docs.godotengine.org/en/latest/learning/features/shading/shading_language.html
I've searched through the documentation to see if there was some way to change the default RIM color (white) to another color of choice such as green, yellow, or red in the shader language. Sadly i have not.
Is it possible to change the RIM color at all in the shaderMaterial?
The idea is that i wanted to make an object highlight a different rim color for special occasion. Say for example Green Rims for healing or Red Rims for taking damage.
