Are you testing with renderingEngine: .coreAnimation
or renderingEngine: .automatic
?
It's expected that renderingEngine: .coreAnimation
will sometimes be incorrect. You should prefer using renderingEngine: .automatic
, which falls back to the Main Thread rendering engine if it detects the Core Animation rendering engine doesn't support the animation.
yes, I forgot to mention that tested with .automatic as well - same wrong result.
Just wanna add to this. I'm also experiencing this issue. coreAnimation
mode does not render the animation smoothly.
This appears to be an issue with how Core Animation itself is interpolating the transform keyframes. If we force this animation to use the expensive "manual interpolation" codepath then the legs are positioned correctly. This introduces other issues, and I'm also not sure how to detect this case dynamically (e.g. we wouldn't want to just "always" use the expensive codepath, because that would hurt performance for all other animations).
For now, using the main thread rendering engine is a good workaround.
Hi When I use
configuration - then animation seems to be fine. But when switch to newer
.coreAnimation
then animation is off. Recordings and lottie JSON files are attached.Which Version of Lottie are you using?
Lottie 4.2.0
Expected Behavior
For .coreAnimation not to mess up the animation (video is attached)
