Copy Collision from static mesh => Orientation problem


I have a skeletal mesh and wanted to apply a convex collision. I saw it is not possible directly, I created a static mesh from this skeletal mesh. In the static mesh, I created a convex collision shape and wanted to use the functionnality ‘Copy collision from static mesh’.

Here is the static mesh :

here is the skeletal mesh after importing :

As you can see the colliding element is not well oriented and I am not able to select the global object, I can rotate simple elements on the shape, but not the whole shape.

Can you tell me what am I doing wrong and if there is a better method to accomplish this kind of job ?

Thank you for reading!

I am really sorry, I am new to UE4, I resolved my problem by using a convex hull in the skeletal mesh.

It seems to work!
