just check simulation time control (under environment) has the first frame defined explicitly especially if you have a number other than 1 as your first frame and non integer frame rates
by default it will have a tick box for use start frame and the option will be grayed out. this has made me sad in the past. with that set correctly the first frame should reset your ice to the state described buy the modeling stack alone. _sam On Wed, Jan 30, 2013 at 10:56 AM, Vincent Langer <m...@vincentlanger.com>wrote: > Hi there, > > i have some pointcaches of underwater float particles and i want to create > a small ice setup which lets me move a null by this pointCloud. > > i want to attach some bigger float pieces to that nulls. > > > i had no success so far. > > the math is not the problem. > > i take the three closest points at the modeling stack and in the > simulation stack i use the 3 positions to calculate the transformation and > orientation. > > but i can not get the null go back to an initial position which i define > by another null at the first frame. > > maybe somebody has done something similar! > > cheers, > Vincent >
