Clip Studio Paint lets you use a variety of default materials, but it also gives users the freedom to create new ones. I often try my hand at creating new tools myself; most of the time, they’re small inventions for personal use (such as brush settings or uniquely shaped guides), but I’ve uploaded some—which might be particularly useful—to the Assets section of the program’s website, so they’re available to anyone who wants to download them.

You can find them on this page.
