Hello-- I am brand new to KRITA amd started using it just this week. I am hoping to make my first large animation but I'm figuring things out first.
For example, when I draw lineart with a brush and use the paintbucket to fill in the inside, I get those little white dashes on the inside of the lineart, like many other programs have. Is there a way to fix this? How do you guys color animations-- by hand?
Thanks!

If your line art is not too thin, you can increase the fill flood, is done by pixels (do one at a time until gets most of the "in-between" spaces), The function is called "Grow selection" in the tools options panel, you can also play with the "Threshold" but that could affect unwanted pixels.

Extra tip: I tend to fill with the "Behind" blending option on the brush, (click on the drop down menu that says "Normal", it will show you all blending modes available, note that painting blending modes are independent from layer blending modes, for this case I'm talking about the painting blending modes, right in the tool bar.
