Does that involve modifying the engine? I’m not sure that’s something I could jump into very easily, but I’ll have to look into it.
EDIT: I think I’ll be switching to the forward renderer, here, after looking into it a bit. I really hope in the future they consider adding custom shader support right in the engine. I’m not an expert, but it seems like the reason it wasn’t there before was because it was using deferred rendering, so now it should be possible to implement!
