Record (for pro users only)
You can now record at your own pace by pressing "Y" button and then pressing it again to stop the recording and then save it to a folder of your choice.
I would use the interact with all icon -> move and then put your drawings on every depth and then while recording, using the arrow keys.
Say you've finished your drawing at 30 depth, and you want 8 frames. Put the drawing on 292 depth and then go back and edit it.
You can do it in an easier way by just saving it to a folder, and then when you are done with all animations, put them on every depth starting from 0.
