Yes

NavMesh is not generated on Physics Triggers

-

How to reproduce:
1. Download and open the attached project
2. Enter Play Mode
3. Open scene view
4. Observe the mesh with a trigger

Expected: NavMesh is generated on trigger colliders
Actual: NavMesh is not generated on trigger colliders

Reproducible with: 2021.3.13f1, 2021.3.31f1, 2022.3.12f1, 2023.1.18f1, 2023.2.0b16, 2023.3.0a11
Not reproducible with: 2021.3.12f1

Note: This is directly related to UUM-10109 - the fix directly caused this behaviour

  1. Resolution Note:

    This was an intentional change that we made to prevent trigger boxes from being included in NavMesh generation because agents and physics bodies can move through trigger boxes and aren't blocked by them.

    As a workaround, one can use a collider masked on specific layers. The performance overhead of that is expected to be minimal.
