Ok, I have tried milkshape, blender, and google sketchup. I have no idea how to add mount points, and do all the other necessary things to actually make my models work. I'd love it if an experienced modeler would make a step by step guide on how to make vehicles/items. If anyone could make a detailed, quality tutorial for any of the three programs above, that'd be very much appreciated.
I know there have been other tutorials made, but they are crap and usually out of date + they dont specify their program's version.
