First: I'm a completely noob in Rendering
I wanted to make a scene with two FZRs in it. I've downloaded the Scene from DS-Autos. I copied the Car. (Selected, Strg+C, Strg+V) And moved it to a free position. My problem now is how to apply different skins. I have copied the Material which includes the skin and put my skins on it. So I have two Skin Materials with 2 different skins. I've selected the faces of the body of the one car (the parts including the skin). But when I applied another Material ID to this part (for the second skin) the skin of the other car is changing too.
I really dont have an idea how to do this. Please help me.
Sorry for my English
