How do you get nHair's cache to update properly in Maya?I'm new to Maya, I have a joint chain being driven by a nHair folicle (made it using Bonus Tools), which is parented to my control rig's NURBS circle. Sometimes when moving the circle the animation of the nHair is not updated to follow. Sometimes selecting the hair system and doing nCache > disable all caches on selected forces an update, sometimes it doesn't. Other times it seems the only way to get my hair animation to update is to put a new keyframe on the parented object.As far as I can tell, the nHair IS being updated, as the IK point/spline is in a new position, but the bones are not.Is there something I'm not doing right? Cheers
