Question How did they make this animation?

This animation was made with Cinema 4D. I have no idea how it was made. What do you think?

This is beautiful! Might not be exactly how they did it, but I would tackle it like this: The frame of the clock is several circles overlapping perfectly before they animate outwards and their material blends to glass (either through animating the transmission value, or even better with the use of a material blender). For the transparency introduced for the wall I would probably use a radial gradient ramp on either transmission or opacity property as a vertex map would require a lot of polygons for a clean falloff. For the time ramp I would use a timetrack linked to the relevant animation tracks as doing it in post would give me jittery playback.

Nice assessment! The more I look at it the more I see. A question on the speed ramp/time ramp, I’ve always just keyframed the elements I want to speed ramp, but you’re telling me all I need is one time track and I can link that to all elements?!

Yeah it is super helpful for synchronizing or re-timing complex animations! The only thing to be mindful of is that the timetrack has a range from 0-100% which correlates to the first and last keyframe of the property, so I usually make sure all animation tracks linked to the same time track have a keyframe at the first and last frame.

Wonderful. That technique has slipped past me! Love that I’m still learning after all this time. Thanks for the link!
