Hey folks, I worked on a script to deploy Autodesk 2026 (the one that uses the named user licenses). We don’t teach Mudbox, so that isn’t in the script...but Maya and AutoCAD is (along with Darwin..what a PIA to get working). I packaged the apps and deployed to /private/tmp/AutodeskApps… I have a lot of logging left in the script as Darwin is a royal pain and can fail at many different steps. I also made use of a lot of variables to hopefully make updating in the future easier. Oh, also did it in zsh.

Hope you all find it useful, or at the very least, a good jumping off point!
