For ref, a method to spawn a bunch of planes behind the player and act as persistent static-meshes which then can be rendered into the RVT, creating persistance, I believe it’s popular/known (Marvel Master): Unreal Engine Basic Dynamic Snow Tutorial - with Runtime Virtual Textures - UE4.25 - YouTube
I’ve also tried the Ray Wenderlich method of using 2 render-targets (capture + persistent), and that works, but not for me (yet); did something wrong apparently…
That aside, I thought it might be convenient to try an RVT, but I can’t see way to (directly) accumulate w/o using any kind of swap-space. Wondering if anyone has tried this?
My thinking here is that I don’t necessarily want to spawn a ton of persistent meshes if I can help it. Tests seems to indicate the overhead isn’t terrible, but I know it’s there…
Suggestions?
