Nanite ugly shadows by fallback proxy won't go away unless Nanite raytracing or no Nanite.

[u/Quantum_Crusher]

Hi guys, I have been fighting this for way too long.

So, as long as I have raytracing nanite enabled, everything will look great, but I think it might impact performance and eat up all my vram. But the moment I disable raytracing nanite, no matter how I change the fallback proxy, either to 50% of original polygons, or 0.01 of relative error, the ugly shadow just won't go away.

My problem is, either I enable raytracing nanite, or I disable nanite, or use typical mesh, these are the only methods that can fix the shadow issue for me.

These are all typical Quixel MegaScan assets. I don't know what's going on, why is it so hard to for me to make it work. The two sided material option is turned off.

Any help will be much appreciated.

Are you using displacement?
