Thank you for your suggestions! I’ve tried a few cvars, none of them resolved the issue.
While pre-displacing or sculpting the geometry is a viable solution for static details, dynamic effects on nanite skeletal meshes should be pretty cool in sci-fi games i think, infinity detial on tesselated surface. If ray-traced shadows can’t handle displacement properly, it could limit their usability in such scenarios.
Thanks again for your help and the warm welcome to the forum!
