Hi Acadia. That problem can occur if the change from the "zero pose" to the "final pose" causes the limbs to intersect the body and/or confine the cloth too much (there are probably other causes too). It might be worthwhile going through the animation frame-by-frame and checking that nothing is going awry (especially around frame 20)... Poser can sometimes be somewhat stupid when extrapolating to a pose... Cheers, Diolma
