draneria··on Show HN: Krita RGBA Tech – Exploring Filter Engines in Open-Source Art
Thank you so much (ノ◕ヮ◕)ノ*:・゚ I am totally not biased in the slightest, but you should definitely try it out if you haven't already (and want to paint)

I used to use both GIMP and Krita, but I switched over to Krita-only when many of GIMP's filters were bundled into the G'Mic plugin, which is now installed by default in new releases. You don't get everything but I'll trade it for the UI upgrade (and everything else) xD

Thank you! I've been researching more about Krita vs other softwares, it might lag behind in places but they are really cooking when it comes to brushes in my opinion. (plus it is free haha)

Damn that really does look cool (。•́︿•̀。) it seems like I have my work cut out for me, I'd love to have that "animated feel" in a Krita brush. I do have some ideas - I might not get anywhere but who knows :D

Exactly! it is really incredible. I've not used Photoshop much, I'd be curious to know how the two face-off in the realm of brush features haha

My apologies Kroltan, I accidentally replied to the wrong comment earlier! It's a shame the project disapeared I would have loved to have seen that :D

Rubber is a hard thing to get right imo, I was trying to paint it for one of the brush thumbnails of a rubber stamp (https://www.mediafire.com/view/46tten5kkzh2i99/Stamp_Diamond...) - and it was really difficult, I still don't think I got it quite right xD So I can't imagine how tough it would have been to try and create that texture using only CSS and JS back then

Could you give me an example? I'd love to know more about the watercolour paint mixing. If you meant the "live tip" settings of Photoshop, you can do all that in Krita too, using the "texture", and "mask tip" features. RGBA seems to definitely be something Krita has over Photoshop, but I could well be wrong!

by the way, there are other softwares like Rebelle that try to truly simulate traditional mediums - bordering on a whole-ass physics engine that works completely different in the backend from PSD/Krita. Unfortunately its a paid software so yeah :s

Added! Thank you for pointing that out (´。• ᵕ •。`)

Ah, you would need to ask them for a concrete answer, but my understanding is that it is completely baked in.

Long optional explanation:

I say that because I think Memileo sculpted the actual brushstroke in Blender (https://krita-artists.org/uploads/default/original/3X/5/7/57...) and rendered lighting at different angles, and exported each as an image.

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!

The cool thing is that you can extract and edit the animated brushtip in Krita e.g. this one "https://github.com/Draneria/Metallics-by-Draneria_Krita-Brus..."

Which means theoretically, you could use photo editing to change the height I think!

wow, that's amazing! I'm gobsmacked you can make something like this with CSS, that is so cool

On the right track but not quite! Every brush in art software uses an image (raster or auto-generated) to paint with, called a "brushtip". Usually, the brushtip only gives information about which bits are opaque, and which arent - the shape! However in Krita, theres another dimension you can define; value, or lightness.

So there's nothing being generated or created while drawing, its just that some very smart people have coded Krita for the "brushtips" to do more as a baseline.

Not every software works exactly the same ofcourse! This is just my beginner level understanding of it all, I hope that helps

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 :)
