As I have mentioned in the title, I'm very new to this kind of programs. All I needed was a super simple and easy animation that a polygon would gain volume with time and become a 3d object. I managed to do it a few times, I think by accident, and here is the video: Here's how I try to do that: After I create the polygon, I press F9 at the first frame. Then I move to another frame, extrude the polygon, and press F9 again. And everytime, I realize I simultaneously extruded the polygon at the first frame as well. So, as a result, there is no animation. It's already been 4 hours while I'm trying to figure out how to do that. I have watched videos but still can't. It already began to lead me to existential crisis. Is there somebody who can tell me how to do that?
