I guess what has been so excellent recently is that there have been substantial structural changes, workflow improvements, technology improvements and yet you can dump roomfuls of old school flame artists on flame 2027 and they know where everything is, work as they have done for some time, and the changes are acceptable and invisible.
I haven’t played with this yet, but if you export the proper STmaps, you can do all the rest in Flame. This is what we do with KeenTools head tracking. That way it is all 2D in Flame, you don’t need to mess around with Alembic or geo, or any crap like that.
