Add Procedural Dirt (to everything!)
In this tutorial I’m explaining how to add quick and easy procedural “dirt” build-up in Blender …because real life is a bit dirty.
Spoiler alert: This technique doesn’t work on flat and empty object. Your model needs to have some bumps or crevices or you will need two objects close to each other.
