i have a rootjoint and below that is my hip joint.

i made 2 cloth objects and parented it to the hip jiont so it moves with it. the cloth works just fine.

but every time i animate the root joint the cloth doesn't move any more, even after i create a new cache.

do i need to batch render to see work? what am i doing wrong here? this has been bugging me for about 1/2 a year now.
