I tried installing ART for maya2018 on mac today
I tried 2 different downloads :
- from github
- from UE4 install
Both had the same UI bugs, making it unusable.
For example, the timeline constantly flashed and changed duration, and the menus were not clickable.
Ended up just re-rigging the mannequin in maya.
If someone has a better up to date solution, please post it here.
