Nanite Mesh Import Times

I’m interested to know what people’s nanite mesh import times are like for meshes with more than 1 million polys?
For me it takes more than 20 mins to import a mesh with between 1 - 2 million polys.

  • I’ve made sure to untick generate lightmap UVs, generate collision and import textures or create materials as I thought they might be slowing it down, but that made no difference.
  • The mesh is already unwrapped with only one UV set and one island if that makes any difference.
  • I’m using UE5 Beta EA2 From the launcher (no custom build)
  • Model is around 700MB FBX

My PC specs are:
Ryzen 7 2700X (8core 3.7GHz)
RTX 2070 Super
48GB RAM
SSD

Any help or even just mentioning if you are experienceing similar import time is much appreciated.
Cheers

These two things don’t add up…

I just exported a 1m triangle mesh with a single UV channel to FBX from Blender, it’s 42.6mb.

It took 15 seconds to import it (I timed it) as a Nanite mesh…

I’m on a 3900x and the mesh/project are both on an SN750 SSD.

Strange, something is maybe up with my export settings or the model itself then. At least I have an idea where to look now. Thanks
