No

Physics Shape incorrectly generates collision edges when the Geometry is of 32-bit Index Format and contains more than 16-bits number of vertices

Package: Unity Physics

-

How to reproduce:
1. Open the “dots-bug.zip“ project
2. Open the “SampleScene“
3. Enter Play Mode
4. Observe the Game view

Expected result: All Cubes collide with the mountainous geometry
Actual result: One Cube on the right falls through the Geometry (32-bit)

Reproducible in: 1.2.4, 1.3.9 (2022.3.58f1, 6000.0.39f1, 6000.1.0b7, 6000.2.0a4)

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- The geometry has 6.4 million vertices
- Not reproducible with a low number of vertices 32-bit geometry (i.e. Cube) (There have to be more than 65536 vertices in the geometry)
- There is one area that has collision
- Without having selected any of the meshes, in the Scene view you can see the collide-able area in green
