Quoting Firas Abu-Jaber
Yeah great way to do the four doors open, but I don't know; if I use this techniqe the rear door would look small, but I'll try any way, for now I made the front door opens before the rear one, you can't open the rear first, but I'll see what I could do... any way great car you have over here, great details specially for the interior, keep it up and thx for the hint.
Ya, that's what I found if you want the back doors to open separately you're gonna have to make a pillar between both doors and hinge it, but if you want the back door to be longer, there cant be a pillar the entire hinge system has to be hidden behind the door. But thanks for reviewing this :)
