How can i paint debris from a texture? I have a substance file and i want to use that to spread things like rock fragments on the ground. I couldn’t find any tutorials. Any ideas?
There is a few ways to go about this in engine. If you want to blend materials you could create a vertex painted shader to use on your meshes you want to paint additional material layers on.
Documentation for Vertex Painting
An additional option is to use the foliage painting tool, which will allow you to use actual meshes and scatter them across surfaces. This options works well in conjunction with vertex painting/material breakup.
