Meshes
Unreal Engine
Collision
You can export collision meshes along with your mesh. Make sure they have the same name as one of the meshes and they’re visible in the viewport.

UBX = Box
Sockets
You need to create an empty object with the name “Socket_
Triangulation
N-gons can be messed up when exported to Unreal. Ctrl+T to triangulate them.
Unreal didn’t seem to reimport the UVs when I tried to reimport the mesh. I had to explicitly drag the mesh from Windows Explorer into Unreal to force a reimport.
