I made a small [addon for Blender](https://forums.unrealengine.com/t/blender-addon-ue-collision-renamer/269653) to handle renaming.

UBX is strictly a EDIT: rectangular prism, USP is strictly a sphere, UCP is strictly a capsule. UCX is for convex shapes, which will likely be most of what you’re doing. If the collision shape is non-convex you need to split it into more collisions meshes until it is.

I use Blender tools, but those tools do use the default FBX exporter.
