Creating custom brushes in GIMP

We will now learn to create and import into Blender our own custom-made brushes and stencils. This will allow us to texture-paint more realistic and detailed shapes and patterns onto objects. In the following steps, we will draw a brush in GIMP and load it into Blender:

1. Open GIMP and create a new image with Ctrl + N. Set the resolution of the new image to 256 x 256, and click OK.

2. In the Layer menu at the top of the screen, open the Transparency section and click on Add Alpha Channel.

   This will allow us to create a transparent background for this image.

3. Select the entire image with Ctrl + A, and press Delete.

   This will make the entire image transparent. We now have a background for our brush. Anything we paint over this will be the shape of the brush.
