[Tutorial] Filling Line-art!

There was a viral tweet going around on how different artists fill their linework so I decided to whip up a quick tutorial on how I do mine! I use this tool in Clip Studio Paint: https://www.dropbox.com/s/3xgy6cft0yztod2/Fill%20em%20Up.sut?dl=0

To use, download and drag-drop into CSP! The rest is as follows:

Set up your linework on one layer, your colors beneath. On your linework, select the little 'reference' lighthouse button. This will tell your fill tool to use those lines as your guide. Then, using any default color and the fill em up tool, outline around the outside of your lineart on the color layer. This should fill up in the approximate shape of your linework.

A couple tips: If it's not filling an area, adjust the closure gap. If it's going outside of the lines, adjust the tolerance or area scaling. It may be necessary, if your work is particularly sketchy, to fill parts by hand. For this I like using the Fill Lasso under Figures! (this is a default brush~) 

You may also find that around the very edges of your canvas, if your linework extends past the edge, you have to lasso outside the canvas itself. That's fine! You can even cut back in on certain areas to tell it where to include and exclude the fill. Play around with it! 

There's also often a tiny 1px white outline where the canvas ends. Again, an easy fix with the lasso fill tool.

Then lock your colors and you can start putting in your flats using a brush OR the fill bucket. Select the 'refer other layers' bucket, make sure that under 'refer multiple' in the tool properties it's set up with the little lighthouse again. This way you can still refer your lineart! 

Tip: You can create a new layer and still use the fill bucket to fill within your lineart. Just use the clipping mask feature to make sure it doesn't go outside the established boundaries of your colors. 

And that's just about it :D I like this method because it's clean, fast, and it goes right to the edge of your lineart, meaning there's no pesky white artifacts left over. Like most filling techniques, the cleaner your linework, the easier it is, but I've used this method for some pretty scrappy sketches before and it works great! Hope this helps :)
