Hi, I have also meet this problem. Affer struggling for a long time, I found out why:
The reasons may be:

  • Nanite

  • No existsed collision.

So what you have to do is:

  1. Make sure you have build collision primitive for your mesh and have both simple and complex collision primitives (although you can set simple for complex);
  2. r.Nanite 0, even though you have turned it off in project setting; (Nanite uses another culling system rather than occlusion culling)
  3. Try to refresh your project, by restart or something similar.
