After many hours of investigation and progress, i have finished the basics for my animations. And with it, I've managed to create and render a full clip out of my moving objects! This took me a lot of time to just let the computer work while i was gone but after about 12 hours of frame rendering, i managed to make a 42 seconds long clip in HD (720p) with 24fps (frames per second). So please enjoy my short but great creation! And thank you for watching! :)
