Check the Realistic Rendering project from the launcher, there’s a curtain material like that.
It looks ok but there’s still a lot left to be desired. Overall I find especially the maximum quality achievable with VXGI to be somewhat lackluster. Personally I wouldn’t give an *** if I had my scene running at 1 fps when that would mean exit baking but right now it just can not compete. Stuff like very good contact shadows or soft occlusion falloffs are still incredibly hard (if not impossible) to achieve with VXGI. I’m also kinda bumped by the fact we can’t use the Crytek SVOGI system which works faster than VXGI for comparable results. It’s great stuff and I continue to use it wherever I can but given the fact it’s not even developed anymore, I don’t know whether to recommend this to anyone but the people just toying with it.
I think it’s going to be more interesting in the next 2-3 gpu generations.
