DoH!
I tried different things but WTK went faster (or maybe he already knew it...)
Yes yes yes! all is in standardmesh files
I guess Col01 or Col02 or both
Bbox maybe? Anyway Lods and shadows have nothing to do with it
I did take the Huey attack and transport in 3dsmax
I made a kind of fusion so UH1assault had the transport collision meshes and Bouncing box files
I tried it in game and i can't tell real differences for now cause UH1 assault vs transport is too little difference
I gotta try with mi8!
*EDIT* I just rebuilt the mi8 with mi8 cargo collisions and Bbox files, tested it in game warden so i had both Mi8's to compare...mmm i'm pretty sure Why2Kay is right...Mi8 seems lighter now
