Collision Collider Not Working When Added to Instanced Mesh in Ultra Engine

[Yue]

 

Description: When dragging an instanced mesh from the assets into the Ultra Engine editor, it is expected that a collision collider can be added directly in the environment by selecting the mesh in the assets. However, the collider, although visible in debug mode, does not have physical properties and does not react to collisions. On the other hand, if the collider is added to the mesh before dragging it into the environment, it is visible in debug mode and functions correctly with collision physics.

Steps to Reproduce:

1. Open Ultra Engine.
2. Drag an instanced mesh from the assets into the editor environment.
3. Add a collision collider to the mesh by selecting it in the assets.
4. Observe that the collider is visible in debug mode but does not have physical properties and does not react to collisions.
5. Remove the instanced mesh from the environment.
6. Add a collision collider to the mesh while it is still in the assets.
7. Drag the mesh with the collider already attached into the editor environment.
8. Observe that the collider is visible in debug mode and reacts correctly to collisions.

Expected Behavior: The collision collider should have physical properties and react to collisions when added to an instanced mesh after it is dragged into the editor environment.

Actual Behavior: The collider is visible in debug mode but does not have physical properties and does not react to collisions when added to an instanced mesh after it is dragged into the editor environment.
