Is there any way to figure out what shader has been applied to a given surface? There are so many, it is kind of hard for me to guess which one it is, just based on looking at the viewport or even a render.

In my update i am including a category in the metadata that lists all the shaders used by character. If that change doesnt make it in, I will create a downloadable guide.
