Physics asset problem

For some appearent reason, everytime I try to export my blender character to unreal, and check the physics asset, I get very big and few collision capsules on the mesh.

I don’t really know why this is happening, this is like still the first time I ever export a 3D rigged character from blender to unreal. and these are the results I get from it.
I just don’t even know what are the following things I need to do before I ever export it into the fbx file. I’ve been trying to figure out what is the cause of this problem for like 3 hours and still nothing good.
I learned how to export my character without losing the bone controllers, but I can’t figure out why are the physics so incorrect. From that size, I can’t shrink em even smaller thant that.
Blender is such a pain at the beginning when trying new things we never did in it before.
I just want to know what do I need to do before exporting my character model to unreal so I won’t have any trouble further… :frowning:
