I remember when I used to rhd swap cars in ror. I need to learn how to edit .dae's without messing up the smoothing groups.
Actually anything B25Mitch worked on (200bx and Sunburst) imports and exports just fine with Blender and has all smoothing intact, as that is his modelling program, for other vehicles you have to apply an edge split. Straight import all i did was hide some parts and turn up the material diffuse from black to white for easier viewing.
Sorry for stealing your screenshot, but I felt the need to FTFY: (imported from here) (pst if u kno wat this is, u kno wats up lol)
