Hi guys, nOOb here. :D
How can I assign multiple materials to one object??
aside from using decals to sort of get the appearance of that, you can't. You have to split your object up, just like how you would have to do in order to manufacture it. Each material is a separately modeled part.
What program are you making your model in? For most CAD programs you need to make surfaces a unique color for Keyshot to be able to treat them as separate materials.
I once did a tutorial on how to do it with creo. I believe that the process is pretty similar for other cad-systems.

Okay, thanks for the replies! :)
