Hi guys
Why after enabling Nanite support my mesh becomes gray and low poly?
Hello Michal_Ratajczak, welcome to the Unreal community.
Congratulations on utilizing Nanite!
There are a few points of troubleshooting I would look into:
RHI (in project settings): If it is not already, I would consider changing it to DX12.
The mesh may be displayed as a FallBack mesh. The Fallback Mesh is the generated mesh used when Nanite rendering is not supported.
Additional specifications can be found here in the documentation.
I hope the documentation helps.
