UCX unexpected behaviour import

Hello

I don’t know why but, when i import this model into unreal, it break my collision (it is just cylinders). Have you got an idea about that ?

This is a screen on my collision on Maya and the UCX imported in Unreal.

Thanks.

Good day Santorr.

This is happening because UCX collision meshes are supposed to be convex. Your collision meshes are concave. Follow this link for example.

You should probably use 3-5 separate collision meshes for each branch, or even better, consider using a more general shape, that does not fit as tightly to your render mesh.

If that resolved your question, kindly mark it as answered and consider upvoting correct answer. Thanks.
