The first blender creative package is finally here! And it is something that I think most people actually need. So behold, two mighty nodes for adding Dust and Damages in your objects!
The project comes with 4 example materials to help you get started with using the nodes. I'd recommend that you watch the video before using it to know how you can use it in your own projects!
I've also made a tutorial on how to make one of these shaders, i.e. the dust shader, procedurally in Blender 2.8 which you can check out here:
