I’m trying to make brushes for vegetation (e.g. leaves), and it appears my only options for brush tips are to use color as mask, which appears to convert the value portion of the HSV of the image used into alpha, or I can just have the original color. The feature I’m proposing is an option to use …

Hi, @Voronwe13 ! Please submit the patch against the version that works for you, preferably ‘krita/4.3’ branch. And I will port the code to master for you :slight_smile:

Hi, all! Here is a testing package for Windows with @Voronwe13 ’s work : https://yadi.sk/d/E1BgAe3-tOfQTg

Hi, @Voronwe13 ! I have a few worries about the patch, and I’m not sure whether we should think about/fix them… Brightness/Contrast options in the texture option work a bit differently from the brush tip area. Is it a problem? Or, more precisely, is it a problem we should try to fix? There is …

I don’t think it’s a problem. Brightness and contrast still basically work how I would expect them to work. I’m not sure textures need a neutral value slider. It doesn’t really apply to the Value option, since the full color is where it is white, instead of the neutral point. I’m not sure ho…

Here’s an image where I used the same color with the reptile brush. First is Value mode. Second is Lightness mode. Third is lightness, but I used the “Color adjustment curves” filter on the texture to bring the neutral value down, but still make the highlights pop and keep the shadows looking som…

[image] Voronwe13: …then it can just be documented that anyone wanting to make new textures for the Lightness option should design the texture with 50% gray as the color portion. Well, it would mean that people will have to make an additional adjustments step when preparing textures. Which is…

[image] dkazakov: Well, it would mean that people will have to make an additional adjustments step when preparing textures. Which is not very good. Don’t get me wrong, I don’t mind additional control, so a neutral point slider wouldn’t be a bad thing. Like I said before, I would be curious t…

[image] Voronwe13: Unfortunately, no. Inverting the texture just changes which part of the texture maps to black/shadows and which to color. No matter what, it still only does shadows. My idea would be to have an additional mode that maps instead from color to white/highlights. Perhaps we can…

[image] dkazakov: Perhaps we can avoid these duplicated Value modes by using HSL+neutral point? If we set neutral point to 255, then it will work like the current “Value” mode, and if we set neutral point to 0, then it will work as “Value (highlights)” mode. Am I wrong? Yeah, I think you’re r…

Okay, I’ll add the neutral point slider and remove Value mode.
