How to reproduce:
- Open the “NavMesh Obstacle Getting Stuck Test.zip“ project
- Open the “SampleScene“
- Enter Play Mode
- Use A/D to rotate the Capsule and W/S to move it along the forward axis
- Rub the Capsule against all four sides of the Cube, try going both ways of the wall (try to go past the corner)
- Observe the Game view
Actual result: The Capsule gets stuck on one or more of the corners of the Cube
Expected result: The Capsule does not get stuck on any corners
Reproducible in: 6000.2.0a8 (6bc6fbc26ac6), 6000.3.11f1, 6000.4.0b12, 6000.5.0a8
Not reproducible in: 6000.0.70f1, 6000.2.0a7
Reproduced on: Windows 11 Pro (25H2), macOS Tahoe 26.0 (25A353)
Not reproduced on: No other environment tested
Notes:
- The affected corners may be random on different attempts to reproduce
- When going to the corner from the opposite side, the Capsule appears to be pushed forward, as if it were inside the obstacle - likely indicating a faulty obstacle normal calculation
- The behavior is the same among different AI Navigation package versions
- Reproducible in the Player as well
