It's always amazing to see what neat brushes are out there; being able to interface with a practically limitless assortment of different artistic mediums through a single universal method (simple and intuitive, no less) never ceases to amaze me. Kudos! I'll definitely give it a try!
Thank you! Last year there was a special breakthrough for Krita, because a contributor called Memileo figured out a way to bake light into the brushes using Blender. They made a beautiful Impasto set (https://krita-artists.org/t/rotating-light-brushtips-wip/649...), their work was a huge help for my own brushes :)
Each rendered image becomes 1 frame of the "animated brushtip", with the option that each frame matches "direction" rather then being "incremental", and thats how you get the faux-light!
