Current Progress of Space-Nebula and Starfield V3 running in Unreal-Engine 5!
Some code changes where requried to adapt the UE5’s Rendering-Pipeline (basically reworking RHIComandLists partly with GraphBuilders and FRHITextures with FRDGTextures). GPU-Volume-Creation did work right out-of-the-box 
Thanks to Epic and all related developers for this great progress and for making all this possible!
