Join Donovan Keith for an in-depth discussion in this video Adding grunge to paint using the Noise shader in the Diffusion channel, part of Creating Materials in CINEMA 4D.
The diffusion channel allows you to add grunge to the appearance of your materials.…When combined with a well-selected noise shader, you can strip your materials of…some of their perfection, and make them look like they've spent some hard time in…the real world. In this scene, we have a teapot that I've…applied a basic paint texture to. It's got a little bit of noise in the bump…channel, to give us some of the surface depth that you'll sometimes see when…you're painting on a wall. But, it looks like no-one has ever…interacted with it, so let's go ahead and open up our material, and activate the…diffusion channel. The diffusion channel takes a black and…white image as it's input. So, in the texture channel, I'm going to…click on the triangle, and load my Noise shader.…
So what you'll see is that, pretty quickly, we're already adjusting the…overall brightness, and darkness of our texture.…Let's go ahead, and turn on our interactive render region to get a more…realistic preview, and what I'm seeing, is this.…
