The easiest way to install Clip Studio Paint brushes is to use an extension called CS Selector. This is a browser plugin that allows you to easily pick up and apply brushes from a variety of sources. The most popular sources included with CS Selector are the Clip Assets Library, and the Anime Studio Community Library. There are also several community-created libraries which contain great resources for artists. Here’s how you go about getting started with CS Selector, and adding brushes from places other than the default locations.
