Few questions regarding static meshes import from blender

Hi there,

I’m kinda new user of unreal Engine since I left Cryengine recently.
I’m actually doing basic test to find a good workflow between blender and UE. I start first with a static mesh with LOD and collision

  1. first thing my LOD1 don’t work. It have been imported well but as a separated mesh in the content browser. Is it normal ? how I can set it to work with the main mesh ?

  1. Regarding the collision the UBX and USX works fine I got respective cube and sphere but the UCX (that is supposed to be custom mesh?) don’t show the correct shape ?

  1. why the letters from the mesh (ex; front) appears as a collision when I tick the option show complex collision ?
