@TartarugaFeliz Yes, these small GIFs were made during our first internal beta-testing sessions with the new software.
How is the Octopus done?
You basically paint all the phases of an animation you need and apply a very concise transparency animation on all of them at the same time. Then you play with the new "Offset" feature and shift the transparency animation fade-in starting points, so you can see each phase separately and only 1 at a time.
Then you group everything together and make it fly around with some other stuff. This is done with the usual "loop markers".
You will be able to test it for yourself very soon.
