How to Fill in Lineart with Flat Colour on a Different Layer
It occurred to me that a lot of people, I think, don’t know this really useful little tip in SAI that lets you colour lineart with the bucket tool while still being able to have separate layers. It’s really great and saves a whole lot of time so I decided to quickly explain this for people who don’t know!
- Make your lineart layer, and draw the lineart. At least one whole lineart. On that layer, select the option that says “selection source”, as demonstrated in the first image.
- Select your bucket tool and look at the settings. Instead of having it set to “working layer”, set it to “selection source”, like in the second image. The bar on top, by the way, is a slider that adjusts how sensitive your colour will be to the lines. Zero is very strict, meaning it won’t bleed out of any lines at all (assuming they’re closed properly), and the higher you go, the more lenient it is. Play around with this a bit if your colour fills in weird on the first try.
- Go to your colour layer, and with your bucket tool, just slap on that colour where you want it in your lineart! It works the same way as if everything was still on the same layer, but you get to keep your lineart layer separate from your colour layer!
