Hi, I'm having an issue where SuperTextMesh only recognizes animations and quads that are included with the plugin. Somehow it doesn't recognize any new ones. Do I need to add it to a list somewhere or is there somewhere to "refresh" the plugin so it detects new STMQuads and STMDrawAnim files?

If you're creating text data objects through the text data editor, they will be recognized immediately by STM, but if you make them through unity's project window, you'll have to go into the text data editor (click the [T] in the top-right of any STM inspector window), and scroll to the bottom and click "Refresh Database". Please let me know if this solves your issue!
