I’m making a game that could make use of a lot of decals, essentially, and I’d like a way to both increase performance and add permanence to the decals by merging those decals into new textures, perhaps on a periodical basis. Is there any way to do this with UE4, or is this just an impossible pipe dream?
I was wondering the same thing. Here are a couple of links to things I found so far. Some of these are indirectly related, but may spark some ideas.

Hopefully these help.
Did you guys found a way ?
