Steps to reproduce:
1. Open the attached project “IN-141609”
2. In the Project window, open “Assets” → “Scenes” → “SampleScene”
3. In the Hierarchy open “MeshColliderSingle”
4. Using 3D object editor override the mesh of previously selected object
5. Observe the Scene view
Actual result: The mesh disappears out of the Scene view
Expected result: The Editor notices the change of the mesh and reload\reimports the mesh
Reproducible with: 2023.1.0a3, 6000.0.74f1, 6000.3.15f1, 6000.4.6f1, 6000.5.0b7, 6000.6.0a4 (77e2e2eea1be)
Reproducible on: Tahoe 26.4.1 (M1 Max), Windows 11 (User reported)
Not reproducible on: No other environment tested
Note:
- In the 4 step the file to override is located at “Assets/Meshes/collider1.fbx”
- Make sure this is the file that is attached as a mesh to “MeshColliderSingle”
- I recommend using Blender as the 3D model editing tool
