Source

Opens a list from which you can select the action source you want to convert to a looped (cycled) skill.

Start and End

The range of frames of animation that you want to include in the action cycle (loop).

Make sure that frames you include in the cycle are appropriate for a loopable skill. The actor’s poses at the start and end frames need to be reasonably close to each other in space. As well, the start frame should have enough pre-roll to allow for a good loop to be made.

Smooth

Makes a smooth cycle transition. Set the number of frames used to smooth the end of the cycle to have the first and last keyframes match (except for the translation of a locomotion skill). A good rule of thumb for this value is a quarter of the difference between the Start and End frames.

Loco

Select this option if the skill you’re looping is a locomotion skill. This makes the skill loopable without affecting the forward translation of the actor.

If you don’t select Loco for a locomotion skill, the forward translation portion is made loopable as well so that the actor would walk forward, then slide back to the starting position at the beginning of each loop.

Process

Processes the action source to make it a loopable skill with the options you’ve set.
