Building any vehicle in parts is much easier than building it from a solid mesh. If I'm not mistaken, your taking that approach.
Pretty much yes. the body is one mesh but the doors, mirrors, hatch, bumpers...ect are all seperate objects. I did this for a couple reasons.
#1 It is far easier to work with, #2 It is easier to uv map, #3 easier to rig and animate.....And also cause if I am to try and animate collision, It would be useless if the parts could'nt fly off the vehicle..Im still not sure how I am going to do this, but I figured that parts like the mirrors and bumper would need to be glued on.
A couple more pics. As of this point I am finished the basic structure. things left to do to the mesh now are add the suspension, some more clean up. and some more detail.
