After you apply motions to character, the layer order will be determined by
auto-calculating the bone structure of the character. However, the layer order
is not always fixed throughout the whole project. You may set layer keys in different time frames
by moving the body parts up or down.
Select a character whose leg swings. With the initial layer order; the right leg will always be behind the left leg.
Go to the time frame before the character crossed legs.

multiple body parts).

layer below target ones.
Move to Top: Send selected body parts to the top layer.

Click on the target body part above which you want to move (you may hold
the Ctrl key to select multiple target body parts).
Go to another time frame where you need the layer order to be reset.
