Sorry for the delay guys, I haven’t opened the forums in a while. I figured out a way to do it, yes!
All I did was download and build Unreal from source and modify a couple of files in \Engine\Source\Runtime\Renderer. You can check the code in TemporalAA.cpp and backtrack from there. I’m a bit busy at this moment, but I’ll need to update the engine version and possibly redo all changes cause I screwed up version control lol, I can give more precise details once I get to that point!
Good luck!
