Thanks for the input guys. Unfortunately, still no luck. The cloth is assigned to the hips as the root translation for the cloth, and there is no scaling/size difference between the t-pose and the animation.
Does your skirt example have bones? Or is it skinned to the models bones? Also, how many verts does your skirt have? I am wondering if I am running into this issue due to the “complexity” of my robe. It’s frustrating how simple this appears to be, but I’ve literally spent dozens of hours trying to do this :eek:
