Ah sorry, we were posting at the same time.
Regarding maya, if you have suggestions I am open. The way I approached it is to try to work along with maya’s native ways, so you create/apply a bella material the same as you do a maya one. Ditto with the camera, you have the bella rollout in the maya camera attributes, and tools like “frame selection”, or using a camera target, should all work as expected.
But we can definitely add more convenience features, just let me know what you would like.
