I've just made a free version of my ambient grunge node available for everyone to download and use. Its's a simplified version of the original tool which will allow you to get dirt buildup effects in the crevices of meshes by making use of the ambient occlusion data.
In this video, I give you an overview of the tool and we also take some extra time to talk about the EasyBPY project (a free module to simplify the use of Python in Blender) as well as Nodevember.
Thanks for watching and have a great day!
