Made with Illustrator and CSS native animation properties. See the code here https://codepen.io/nwozniak/pen/zYrqZLz
These Lottie animations were made as app loading screens.
Left: Kynd app, a niche dating app. The design was created in Illustrator and animated in AfterEffects. It was then exported as a Lottie file, which was compatible with the app's React Native codebase.
RIght: In order to give the animation a 3D feel, it was created first in Cinema4D, rendered with toon shading, and then exported to Illustrator, where image trace converted it to SVGs, which were convertible into a Lottie file in order to be embedded in the website and within the app.
