Krita's v4.2+ RGBA brushtips let you paint with dimensionality, and it's a technology that Photoshop doesn't have (≖‿ゝ≖)

It lets the creator do things like emulating light direction, making brushstrokes look 3D.

I used them to make a set of metallic brushes. If there are any FOSS artists around, feel free to test them out.

(p.s. Yes, I am learning Github so I probably made repository mistakes - apologies in advance lol)

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 :)

Lovely textures, thank you for sharing. Will try them out in some generative art projects I'm working on!

Great work! I have been looking for an excuse to try out Krita. This just might be it. Shameless plug: I am also a sucker for metallic aesthetics, and I made this FOSS library to enable realistic metal textures on the web (for buttons, cards, input elements, etc.): https://www.metallicss.com

Honestly, I’m most impressed by that fantastic demo gif.

Just a small favor please: in your README.md file, on the first mention of word Krita, make a link to Krita repository or website. Thanks.

So what does it do? Create a normal map while drawing?

Very nice, I approve of anything that goes against the Material Design hegemony.

One question though: there's a (relatively) large delay updating the demo when I change the convexity. Is this something that comes from the update script or is the effect itself slow? Because I don't think I've ever seen a CSS effect that takes a half second to update before.
