Hello, are these steps the same for the lineart brushes? Can i have multiple colours?
No, to do that you have to use another method that is simpler, such as just adding a single line of code to the canvas widget
But even so, it's not possible to draw like that because it causes a bug due to programming language limitations; it makes the marker strokes appear on top of the line art brushes
As far as I know, there's no way to fix that, so it can't be done. But if you still want to do it...
You need to open the properties of the canvas widget and select the "prototype" option, which will open a section where you need to open its scripts
Within the entire line of code, you have to look for the if and elseif functions of the brushes and place this in between the lines of code
