Hi all, I am fairly new to Krita and I was looking to get that perfect brush that would fit my style well. I made a wee selection of brushes and I stumbled upon this tutorial, which I really liked so I made that brush.
And it works just fine with a small-sized brush up to 100px, if I go above the lag is way too big. I checked my stabilizer and it is turned off, so that is not the issue. Any idea how to stop the lag?
Anyway, the original artist that this brush is inspired by is this youtube, so if you guys have any suggestion on a similar brush, please do tell
I also tried recreating Sinix’s Corel brush in krita (it’s probably different as I haven’t used this particular tutorial). It’s part of my free pack:
Mixing paint like this requires using smudge brush engine which is quite performance heavy - also we can’t use CPUs multiple cores there yet, so even with a good processor it may be hard to have them running smooth over 100-200px with low spacing.
The best you can do is go to brush settings(F5) and make the spacing bigger in brush tip options. If you are on 0.02 which is the minimum, you can easily change it to about 0.08 making the brush 4 times faster.
At least for me that was the biggest spacing acceptable, though in case of smudge brush, changes like this requires tweaking other parameters to compensate less frequent brush stamps.
Thank you! My computer is on the good end tech-wise but I did not know that there is a CPU limitation in place with the SW itself. It seems like I will have to play around with the brush, as yes the spacing fixed the lag but it is not quite it now What other parameters do you think is worth tweaking?
But your pack has very similar brushes indeed, so in the meantime I have new toys to experiment with, thank you very much for that. Cheers!
I’m no expert when it comes to smudge engine. I prefer working with pixel engine (and it is multithreaded since 4.0).
As I said I believe it’s possible to compensate less stamps with making other parameters like color rate or smudge length stronger - but I can’t really tell you which ones, as I’m not that experienced with this engine.
I don’t think there are any other things that influence performance this much. Size and spacing are those two obvious ones as one forces to change more pixels at the same time, and second requires making the whole stamp computation more times a second.
Things like density and pattern can slow the brush down as they introduce some more decision making while computing a stamp, but I don’t think you use them, as you were recreating Sinix’s brush.
So my advice would be to try to fix the brush with as high spacing as possible, or start in low resolution (either of canvas or the object you draw) and then upscale it once you have colors blocked and you only need to do rendering (which is done with small enough brush).
I’m not a big fan of instant preview, so I won’t recommend it.
Or just check out pixel engine, as it’s both multithreaded and easier to compute. And you can use this bonus computing time for some textures and RGBA tips. But I don’t think this will help in terms of recreating the Sinix brush
What other parameters do you think is worth tweaking?
