Raytrace Volume Block

Hello, Do we have some volume to say unreal apply all raytrace cool stuff inside that volume and whatever out of that volume just act as no raytracing and do normal build lighting out of that gizmo ?

Unsure what you mean, if your asking if raytracing is applied only to a box area, no, its always the entire screen, but, you could, if you can modify the engine

Yes, I mean exactly that, something like a" lightmass importance volume " or post process volume, so we just limit raytracing apply inside that volume. it will be good for the situation you want raytracing for only forground characters and in background a fast light baking solution.
