How to make objects independent? In Cycles, I imported a car, which a bunch of parts (in .obj format) I assembled together.

For some reason, when I apply a shader to one part, it does the same to  a bunch of other objects, like the ones with the same color or property.

Could be because in this editor where I put the vehicle together, all the object's names are the same or something?
To add multiple materials to an object which I believe will help, do the following:


Select different faces.






After preparing your various materials, select a material and press "apply."

Tadaa!



I really hope that helps. :)
