1: Yes, I verified that it happens in a clean project. I created a first person shooter template and replicated the issue.
- Create a static mesh object which
has at least two different material
slots you can assign to it. - Assign two different materials to the static mesh object (element 0, element 1)
- For each material, assign it a different physical material
- Create something which will run a line trace against the static mesh and retrieve the physical material you assigned to the particular portion of the static mesh. In my case, I created a line trace to occur at the FPS actor foot position
