Join Donovan Keith for an in-depth discussion in this video Creating a brass material using the Noise shader in the Bump channel, part of Creating Materials in CINEMA 4D.
Not all surfaces are perfectly smooth. In fact, very few are.…The Bump channel allows us to add the appearance of surface imperfection without…having to model in all of those details. In this video, we're going to try to…create a scratched brass material. Here are some reference images.…As you can see, our reflection is being broken up by the surface imperfection.…Some look like scratches that are heading in a very specific direction, and then…there are these larger just sort of general bumps.…We're going to focus on re-creating those linear scratches.…
I've taken the liberty of creating a simple brass material as our starting…point, which we're going to add some bump to.…Go ahead and open this brass material. Navigate to the Bump channel and turn it on.…In the texture pull down, select Noise. And what we're going to see almost…immediately is a bumpiness take over our service, almost sort of a cellular look.…Now, if we open up this material, we can take a look at what's causing this.…We see that we get a black and white image, that looks kind of like film grain…
