![]() So I modified GIMP's smudge tool, followed MyPaint's algorithm.Īnd as I drew above artwork, I found that "No erasing effect" parameter is necessary so I added it. The only software with this tool I had ever seen is Krita (color smudge brush with smear mode). Similar examples: Watercolor in Paint Tool SAI and many Japanese softwares, Krita's color smudge brush with dull mode.įor a long time GIMP had no such tool, but newly added MyPaint brush in 2.9.4 filled this gap.īut how about Type 1 with coloring ability? Few softwares have it. ![]() If we add coloring ability to Type 2, this forms "Watercolor" tool in many softwares.įor example, this is the algorithm of MyPaint's smudge. Havn't tried yet.Ĭommonly there are 2 types of smudge tools in paint softwares.Įxamples: GIMP's smudge tool, "Finger" tool in many softwares.Ĭalculate the average color in an area, and fill the next dab. ![]() "No erasing effect" may be useful in watercolor type smudge too. Without "No erasing effect", smudging on the gap will diffuse its transparency to nearby pixels and it's difficult to remove the gap. In the left image, there are transparent gaps between dark gray and red areas. Inspired by Paint Tool SAI, Oekaki Shi Painter, and Harmony. In Paint Tool SAI, you do this by heading up to the Selection drop-down menu. (Tip: smudge tool is very useful to draw hair and flames)Īnd this shows why "No erasing effect" matters. Paint online with natural brushes, layers, and edit your drawings. on as few layers as possible, as the colors blend beautifully together with. Two artworks with similar painting method, only different tools. Otherwise it will be nearly the same as normal brushes. It's better to keep Flow under 30, or control it by dynamics. Also compare this smudge tool and MyPaint brush(which is watercolor type smudge). If someone agrees to make this as an official feature, I may talk to GIMP developers. This is useful to fill the gap between two color areas.Ĭurrently I made this just for experiment and it's not very robust. If enabled, if smudging will decrease alpha of some pixels, don't decrease them, thus don't erase existing pixels. (To simplify the work I picked a currently-unused parameter and didn't make a new one.) Of cource it can be controlled by brush dynamics. The more it is, more foreground color will be blended. One is "Flow", which controls the amount of brush color. I did this by modifying GIMP's core codes and building by myself. (I mainly use GIMP for painting, so the power of a brush engine is important to me.) Because I thought this can make a different taste from "Watercolor" type smudge when drawing images. Well…that’s all of the default brushes for the normal layers.I customized GIMP's smudge tool, to make it not only smudge existing color on the canvas, but also blend brush color on it. Although, if you use the Water tool as a blend and blurring tool, it will be perfect (only when you’re using a tablet unfortunately) because the Water tool wont only blend and blur, but it also colours, so it never actually erases colour, but spreads it instead. With a mouse, the first click on colour will only make it blur and blend, nothing more. It takes awhile for this to take effect and quite a bit of drawing over strokes to achieve this however, and that INCLUDES using a mouse. It begins to erase the colour on that layer and match it with the one(s) below. While this tool is mainly for blending and blurring, the blur tool has a bit of an eraser effect. Now, here’s WHY it’s second only to the Water tool. Those that don’t have a tablet, you can easily use this tool for blending and blurring, since that’s it’s only purpose. I’ll go into why here, because if you can’t use the water tool, then I’d suggest that you use this tool, as this one is the next best for it. Though, if you recall, in some previous posts, I recommended the Water tool over all the other tools in the program that can blend. So, that said, it’s good for effectively blurring and blending colours to get rid of sharp cut-offs if and when you don’t need them, the only effect pressure sensitivity has on this brush is stroke size, which in this case is how far the blending effect extends outward. Anyway, so yeah, this is the primary tool for that, and that’s literally all it does. It’s the only tool in SAI physically DESIGNED to blur and blend and nothing else (as I swear I’ve gotten colour out of the Water 9 and Water 10 tools, so I swear they’re not just for blending and blurring). As you can see, it’s SAI’s primary blending and blurring tool. There…really isn’t much to this tool at all, but here’s an example of it at work:Īlright, that’s the blur tool essentially. Alright, today it’s the last of SAI’s default brushes.
