Starzee - I think you once mentioned you wished Procreate had a colour fill tool (paint bucket tool) so colouring in a bordered area wasn’t so tedious.
Well, try this. In order to use the fill tool in a vector program you need an area enclosed by lines. In Procreate, if you have a clearly outlined area that’s fine. (But if you don’t you can also draw a selection area) Imagine you have a simple cartoon sketch with solid outlines. We will be selecting each space and filling it with colour. I prefer to paint into another layer below the lines layer as it makes painting easier than painting just up to the lines. But you could paint directly onto your Sketch layer if you like. When you paint under the lines you have more lea way when painting. Here we won’t have to worry about the lines at all.
I add a new layer to paint on and drag it below the sketch layer. Activate the sketch layer and then tap the Selection tool (shaped like a ribbon “S”). When you activate the selection tool a new tool bar appears at the bottom. Just make sure “Automatic” is highlighted. Tap twice within a section you want to paint in. (Why you have to tap twice I don’t know. Maybe it activates the layer before making the selection?) Anyhow, That selected area will turn blue. If you want to add another area to the same selection tap once in that area, too.
Now activate your new layer below the Sketch layer. You will see that everything except the area you selected is covered by stripes indicating you can’t paint there. Pick any brush you like, it can be even bigger than the entire space you want to fill, pick your colour, and Paint with abandon without worrying about the lines at all. The area will be filled and nothing else will receive any paint. That’s as close as you can get to a fill tool.
Sometimes you may want to paint with a brush bigger than the size of your selected area in order to adjust the size of a pattern in the brush, or stamp.
One thing different, though, is that the colour you fill with doesn’t have to be flat, that is, not all one solid colour. Your brush could be partially transparent and you can build up density in certain areas to create 3D contour or shading. You can even pick another colour or shade and paint just part of the selected area. You never paint beyond the lines.
It’s easier to do than it is to explain and I think you will see it offers much greater potential than a fill tool.
