Hi moe,
You can render it everywhere, but if you added “frames” to a Doodle, this triggers different states. Also: each window in the editor view (perspective, front, back, etc) has it’s very own Doodle.
If you like to specify how it is set up in your scene, delete everything in a copy of that scene but the doodles, and share it here. We might find much faster what you need.
If there is more need for something else, perhaps set up several doodles for each Key Position and use the display Tag to ‘blend” among those.
Another way, perhaps too much work, is to export the Doodles and animate them in an Editing app, FCPX, Pp, Ae, Avid, etc. Then bring them back on a Front Object, with a alpha channel.
All the best
