描述

  1. Starting with the Stride "Terrain" sample.
  2. Added a vehicle model fbx file.
  3. Used Add Physics asset / convex hull to create collider
  4. Used this collider with a rigid body, works fine.
  5. Tried to use this collider with a character component, and it crashes the program.
  6. Made a much simpler multi box collider for the vehicle (one rectangle and four cylinders).
  7. This simpler collider also crashes the program when used with a character component.

研究方向
Examine the stack trace attached to the issue (strideCharacterWithComplexColliderCrash.txt) to identify the exact crash location. Look at the CharacterComponent class and its interaction with collider types, specifically how complex colliders (convex hulls, compound colliders) are handled. Reproduce the crash using the described steps and check if any assumptions about collider shape are violated. Consider reviewing recent changes to the physics system that might have introduced the bug.
