Creating Flats Using the Bucket Fill and Paint Unfilled Area Tools

In this section, we will use a bucket fill tool that uses the reference layer as its boundaries.

To complete this section, we will need a file open that has a set of lines on a layer we have set as a reference layer.

Also, note that sometimes in the Clip Studio Paint interface, the reference layer is called the Referring layer.

Complete the following steps to create a custom bucket fill tool that conforms to the reference layer:

1. Select the Fill (paint bucket) tool.
2. Select the Refer other layers tool.
3. In the Tool Property palette, find the Multiple referring options. Select the Reference layer icon for this option.
