C:\Users\enenra\AppData\Roaming\SpaceEngineers\Mods\testmod\Models\Cubes\large\Scene_BS1.fbx: WARNING:
LOD model Models\Cubes\large\Scene_BS_LOD1 is missing
Normal LODs work normally so the only guess I have is that the cause is that MWMB is still hardcoded to only accept basename + _LOD1/2/3 etc., and because the basename would be xyz_BS_LOD1 and not xyz_BS1_LOD1, it would break. And the only way to fix that is by adjusting the MWMB or biting the bullet and working on support for multiple LODs per BS à la #290 .
