Hello,
I have found a strange bug with the new versions of babylon.js (I tried on version 8.8.5)
When an animation is launched, if do a goToFrame to the group, it will not move the current frame of the animation to the selected frame.
there is an example where each 500ms, i’m going to frame 2 on my animation with a total of 30 frames.
Hope this helps !
