objective : solve the shot
Recently I am developing a shot inspired by “Masterclass: Crumpling and Tearing”(http://www.sidefx.com/index.php?option=com_content&task=view&id=1540&Itemid=305) [sidefx.com]
In two video called walkawayBeauty.mov and walkawayUVs a piece of cloth was deformed and teared to simulate some kind of destroy effects. The author caculate the distance of the moving point. If it starts moving, it stores the frame number and nails down the UV which is projected to the cloth and it is nolonger moving.
My problem is : how can I nail down UVs to the cloth which starts moving?
thanks in advance.
