Hey, there is something I wonder for a long time.
Imagine I have a random material on a mesh, is there a way to add a second material on this mesh without losing the first material and without editing the first material (that can vary a lot depending on the mesh)?
For example the orange outline on the editor when you select an object: if I want to do something like that in the game do I have to add an outline-function to every single material with a parameter to know if the object is selected, ect… ? Or is there a less laborious way to do it?
Thanks for your help
