I'm running into a little roadblock when it comes to implementing surface imperfections on my object.
The following are the texture files I have for my initial material:
Using google and some video tutorials I was able to setup the following material using these textures:
Marble material on Suzanne:
Now, I also have texture files for some large cracks to use as surface imperfections:
My initial instinct was to implement this as a second material, and then I would be able to apply both materials to the same object via some sort of layering system.
However, from what I can tell it looks like you can only have a single material assigned to a given face of an object in blender.
Assuming that is the case, how could I best go about implementing this second batch of textures into my initial material to act as surface imperfections? Or if I'm mistaken and two separate materials is the way to go, how do I go about utilizing both of them in this case?
Any additional insight/advice/pointers are welcome. I'm sure there's more than one way to go about implementing something like this.
