When I am painting brushstrokes, strange grid like artifacts will appear, making the shading cut off against a straight line. The even bigger issue is these artifacts won't go away after I hit Edit>Undo or close the program. I have to keep manually blending them back in the artwork. I'm not sure what I can do to fix this. I took a screenshot to show what I'm talking about. Does anyone have any advice? I really want to like this program, but I just keep having to deal with more and more issues and it's starting to feel not worth it.
does it happen with every brush type out there?
I remember running into something similar (like the document got slashed into squares some of which weren't available for painting in) while trying real watercolor when it debuted after which I never touched this tool.
most painter brushes should not break your documents; there's a lot of underlying frustration with this program in general though that never practically goes away.
if you go under window -> brush settings -> "general" palette, and take a note of the brush type that produces corrupted images, it might help you avoid similar issues when painting later (just by avoiding this entire brush type), but I can't really comment on what's going on;
it's def. not normal.
Yep ipetcats is right, if we can get an idea of which brush/settings you are using we can find a setting to improve this and/or tune out the noise. I think you are using a brush with 'stroke attributes', which could be using a 'composite method' that produces artifacts...
Sorry for not replying earlier. The brush I am currently having the issue with is the Acrylic Gel Wash. I've also been using Glazing Acrylic, but haven't noticed any issues with that yet. I had seen the issue to a lesser extent on an older version of Painter with some of the airbrushes and Paint Bucket, but I haven't had those come up again in the 2020 version.
Yeah I'm getting the samething, especially if stroke opacity is high (closer to 100%). I was able to work-around the issue by going menu>window>brush control panels> brush media > stroke attributes...in the stroke attributes panel I changed the merge mode to 'multiply'. from what I could see the look of the brush was nearly identical without the artifacts, so maybe this is a possibility for you?
I'll give that a shot and see how it goes. Thanks for the advice!
