Hey, i am having troubles looping a run cycle for an animation, the current character moves forward in the cycle. Ive tried everything that I can find, from copying and pasting keys in the dope sheet and graph editor. every time i copy the frames the character messes up and his limbs go everywhere. I was wondering if its because I've actually made him move forward in the animation rather than putting him in a status position and moving it after?

Please help! thank you!
