Can anyone steer me to any information on using masks in ART? I’m finding little to no info on ART in general, any online manuals?
There’s a wiki page at https://bitbucket.org/agriggio/art/wiki/Localediting providing a quick intro/overview.
For more in-depth information, you can check out the videos at https://www.youtube.com/playlist?list=PLZOdZMT41b7Wr4aPKpQutXQY9ImTl_N1J (they are in French, but YouTube provides automatic English subtitles, so they can still be useful). Finally, you can always ask here
