>>3172Drawing lineart with a mouse is hard, which is why I would prefer start of with paint scatches and then draw a lineart on top of paint layer. To paint with a mouse, you need to use a custom brush that is shaped of a ractangle. The ractangle shaped brush also need to be tilted at 330 degree. The corner edges from tilted ractagle allows you form a fine stroke while painting. There's two process how to achieve this. First you paint the first stroke and then paint another stroke overlap the first stroke with a tad margin slightly skewed from it's orginal position. You can also turn the second stroke into an eraser or white paint. Depands on what you want it to be. You can refer to pic related to know how it is done. By the way, a 330 degree tilt brush angle is what I used most of the time. But sometimes I need a 90 degree ractangular shape brush too just incase if 330 degree brush stroke doesn't produce the best result on certain angle of a stroke.
