Well, I tried to generalize the question, but didn’t achieved much. So for example, how do I add a cut on a tree my character is chopping down? Or add a hole in the wall next to where the bomb exploded? I guess I should add a 3d object that overrides a part of a tree/wall as transparent and then add a scar, but I have no idea where to start.
Thank you!
For scars, bullet marks, visible damage, etc. it’s easy to use decals, see below the link:
Creating a hole in the wall is a bit more difficult to do properly, so if you don’t specifically need it, I would advise against doing that and stay with just the decal.
