So I've been using the Substance plugin for Maya 2018 on Mac and it was working fine until I changed what I think was called the Engine Control from 'software' to 'hardware' which then gave me a pop-up saying that Maya needs to be restarted for that change to take effect.
Upon restarting and loading up that save file Maya crashes to desktop. Even opening a fresh Maya and it will crash. I deleted all my Autodesk Maya contents from Applications and re-installed Maya. Booted it up and it works. I re-installed the Substance plugin, boot it up and it crashes. I delete Substance from plugins, boot it up and it works.
Heelllp
I guess my best course of action for now is to just use Maya 2017 and download the Substance plugin for that?
