Setting up your brush to perfectly reproduce the desired art style can require a lot of tweaking as well as trial and error. Once you have found the correct settings for your brush, you will want to reuse it throughout your project for consistency. You can do that by creating and using brush presets.
Harmony comes preloaded with many brush presets which you can select from the Tool Properties view. It is also possible to create your own brush presets by configuring your brush, then saving it as a preset.
Brush presets are saved in your preferences. You can also export your brush presets into an .xml file, and import them on a different workstation, allowing you to share your brush presets between the different people collaborating on your project.
