I was trying to get a model I made in blender, and I noticed that a large amount of vertices and faces were missing.
The model itself has many, but I then noticed that other, smaller model had the same problem.
I’m using version 2.6 of Unity.
A mesh can at max have 64k tris and vertices, after import (ie once the data are correct for realtime 3d processing, no longer “modeller numbers”)
