Worked like a charm, i guess today is not my lucky day, since i did everything wrong what i could do wrong with mobhack and lbms
Tested it with some more pictures and it worked perfectly, i converted the pictures of a Z Battery and an armoured car with tulip attachments and had no problems.
So i guess i will now implement some new lbm's and build some new vehicles with mobhack.
P.S. thanks for the fast help, without you i would still try to figure out where the problem lies.
