This is a low polygon car. It's a Chevrolet camaro created from a blueprint. It was made in blender so for best results use blender and the .blend file. .obj will work but needs a seperate .mtl file for materials. .dae works aswell without any extra file fbx, ply and 3ds; I have tried these with blender and they work okey but some of them don't import materials.
I strongly recomend the use of blender and .blend for the same result as in the pictures.
Blender:Change of materials is easy, just choose which color you whant to change and press select in edit mode, then, pick a new color and press assign.
