Step 2. Set Your Opacity

Adjust this slider to set the opacity for the Roller Brush.

Pro Tip
If you want to fill with low opacity without getting overlapping regions, turn your Opacity Slider to 100%. Then, tap on the Layer Actions (•••) button on the layer you want to add your fill to. Change your Paper Blending to Multiply and now you can keep adding fills to this layer with no overlaps.

Step 3. Fill

Start drawing and you'll be able to fill entire regions with a single stroke.

Pro Tip
Always double check your layer before adding fills. You can always select the layer you want to add your fills to by double tapping on the Layer in the Layer Toolbar. It's smart to keep your fills on a separate layer than your line drawings to keep your project organized.
