How to export a plane collision model using Blender?

[BRONYA]

My collision model is not functioning correctly，The model appears normal when viewed in ModeView2, but it clips through objects and the collision model does not work properly in the game.When the airplane is treated as a static object, the collision model seems to be working fine.I have bound the collision model to a parent skeleton and created an armature animation, and I'm unsure how to troublnulleshoot the issue any further.Is there anyone who knows what to do? Thank you.
