I’m having issues with this, and I’m finding it that because I’m able to somehow load a dummy map with nothing on it, that the problem lies in specific materials. Some specific materials crash when compiling in the D3D12 RHI and raytracing on. I’ve not narrowed down why this might be (as I don’t know how materials work at their very core), but I think the problem is some of the materials are too complex for raytracing to handle.
