I am experimenting with a very simple bike rig test that I have prepared in blender as follows:
I then imported it as a Skeletal Mesh and added the following physics asset:
The wheels are hinges and the simulation behaves as expected.
But when I drag the physics asset to the scene however. It looks like this: (the collision shapes are configured to not collide with one another)
It has to do something with the pysics because when the simulate physics checkbox is off, the bike looks normal again.
When I run the game though all the parts pop back into place immediately and look again as expected:
Is there something I should be aware of that can cause this behaviour? It looks like some sort of collision is happening within the object or some sort of offset?
