I need some help on this weapon, an anti-tank launcher the same as the SRAW. The problem is when I export it and tested in Editor, the collision mesh does not make contact with the ground. I mean does not act as the same as other falling weapon objects I.E. Eryx, ammo kit and the medic kit. In-game it says "When calculating inertia, there is no collision mesh for object: falling weapon" I have set the collision mesh to geom1: lod 1.

Here's the hierachy:
CODE
root_bundlemesh_USATP_defeater
         geom0
           lod0
             usatp_predator=0
                 1
                 2
           lod1
             object07
          geom1
           lod0
               usatp_predator=5
                  1 - Remove this!
             lod1
               usatp_predator=6
                nonvis_
                   col0
                   col1
                   col2


To make it work remove the indicated number on hierarchy. Only the main mesh should be there along with the collision meshes.
