Loop between 2 keyframes in a middle of animation
I have this animation
1st keyframe : 0s
2nd keyframe ; 30s
3rd keyframe : 35s
4th keyframe : 4 mn
5th keyframe : 5mn
I would like to know how could i loop between the 2nd and the 3rd, the loop would last 3.25mn until it reach the 4th keyframe to continue the animation.
Is it possible to achieve this with simple expression ?
