[Help] Vehicle Wheel Physics Issue

[anonymous_user_66e1b531]

Below image shows the rigged APC vehicle (pivot center, position (0, 0, 0), rotation (0, 0, 0), and free xform) export in cm (binary, fbx 2014/2015).

Physics:

While I doing the physics using the basic workflow, it doesn’t work at all.

Basic Workflow: Delete all the collision, then only add in collision afterwards.

Issue:

The wheels totally ■■■■■■ up.

Other workflow: Reset the Root Collision to Multi Convex Collision, and Wheel to Sphere Collision.

Result:

I don’t know what exactly causing these issues, but I think reset do managed to fix it somehow…

And I tried to set up the animation blueprint and blueprint to the vehicle

I set up the wheels and executed console command: PXVIS COLLISION to see where the collision locating… I manually change the offset of collision to match the wheels.

As you can see, the APC collision doesn’t seems working.
