How to Add a Shader to a Specific Part/Area of an Object? So let's say I create a material in Cycles and let's say, I load an image texture onto a sword. It perfectly fits, all good.

So how would I select an area of the sword, let's say one part would be steel, and the other part would be (leather)? I just need to know how to add more than one shader on different parts of the object.

Otherwise you could mix two shaders depending on a texture:
