Editor freezes infinitely when importing a very high poly mesh (around 6,000,000 tris). Nanite is enabled in project and mesh import settings. Is there something I’m missing?
Anything over 1 million takes a while to import, how long have you waited on the import?
On the import settings, you can try unchecking anything that would do additional processing on the mesh. Basically turn off anything that says remove, build, generate, transform, combine, etc. It should process much faster.
The editor probably freezes because your mesh isn’t triangulated when you import it.
If you skip steps, then the engine has to execute the steps. And that takes a long while on that high a count of verts.
