I found a list of AE supported features for Lottie on other platforms https://airbnb.io/Lottie/#/supported-features, what does lvgl support? Does anyone have relevant experience and documentation?
LVGL renders Lottie animations using the ThorVG vector graphics library. This means the supported Lottie/After Effects features mostly depend on what ThorVG supports rather than LVGL itself.
So it would be best to check the ThorVG documentation or feature list to see which Lottie features are currently supported.
