I have confirmed all the above version numbers are higher than the ones listed, and that I have DX12 installed, and it exists in the folders listed. I have set my RHI Default to DX12, I have unchecked DX11 so that only DX12 is enabled. I have trashed all the temporary directory like Intermediate, Saved, etc. And I am still seeing the behavior of previously enabled nanite meshes having a splotchy appearance when it is enabled. I have tried disabling it for these meshes, and then re-enabling it, and the results are the same Any other potential suggestions?
