In the picture above you can see the keyframes for a walkcycle.
The start and end keyframes are the same as it sould be in a looped animation(frame 0 and 59). The two keyframes on the far left and the far right(-13 and 72) are needed for maintaining momentum during the loop, as without them the loop wouldnt look smooth.
I now need a way for them to influence the animation without increasing the animation length and without these two keyframes being played after exporting. The animation should only be played from frame 0 to 59.
