Santiago Pereira shows how to create a shader network for paint blisters and rust.
A new tutorial from Santiago Pereira (Sanctus) shows how you can create procedural textures that include adding paint blisters and eventually rust in Blender.
The tutorial shows how you can animate the attributes so the material will appear like the paint is blistering and then show through to some rust underneath. Help support Pereira on Patreon.
