thanks, the new model of the Flak Opel looks great

. I guess atm it is too complicated to export complete vehicles to 4ds format, because of all the dummies for wheels, collision, weapons etc.
But if you just copy the sectors for the cab with interior side and the flatbed, you have a simple hull model that should make no problems to be exported. This hull model can be attached to a base model made from the original la_opelfaf. I made several of these base models, where I removed sectors by scaling them to 0 with a hex editor. You can also make textures completely transparent.
This way I put the body of the Praga truck (la_praga.4ds) on a base model of an Opel with no canvas. First version was released with occupation mod El Hamma (EH_NV_occ), later version with transparent (or better to say no) windows isn’t released yet.
With attached models we can make some changes and improvements of existing vehicles, e.g. better detailed wheels/tyres or so. It also would be good to have a better Citroen model, as the one from HD2 is a strange mixture of prewar and postwar cars. The rear should look more like this.
