Question about curved line cleanup in Krita that took me 6 hours last night
Trying to smooth the edges on a 3000px dragon sketch in Krita, the antialiasing kept ghosting no matter what brush I used, and it turned out the fix was just turning off stabilization, which took 6 hours to figure out for a 10 second click, so what is your go-to trick for clean line art in Krita?
Turning off stabilization is exactly what caused your ghosting, not what fixed it. Stabilization is what keeps your lines from wobbling, and if the brush is lagging behind the cursor by even 10px, of course the edges look soft and doubled, that's the delay you're seeing. Learn to work with it set to basic or at a low strength instead of killing it outright, because raw mouse or tablet input will always give you rougher curves than a stabilized stroke. Six hours to find a fix that just turns off the one tool built for clean lines is a bad trade, and you'll notice the problem come back the second you try a slow, careful curve on that dragon. The real trick is tuning the stabilizer weight and your tablet pressure, not throwing the whole feature out.
