FK overlap doesn't loop

Post by dyanez » Thu Jul 11, 2019 5:15 pm

Hi all,

I have come across an issue related to FK overlap. I'm trying to animate a hair rig that attached to a character in a walk cycle, but the FK overlap doesn't let me loop it perfectly. The end frame of the cycle doesn't match the first frame, so it looks like the hair just jumps. Is there a way to make it loop with FK overlap? Is FK overlap automatic only? Is there a workaround?

The overlap is a dynamic, which means its movement depends on the motion of other elements BEFORE.

At the beginning of the loop, it doesn't have previous motion to compute, so it just initiates the movement. At the end of the loop, it's already moving, so it's not in the same place.

Just duplicate the keyframes of the loop once, and use the second part to fix this issue, not the starting one.
