Hi need help with some questions on dynamics. as refernece i have created 3 dice to roll along a table. the first time i applied the dynamics to it. ( gravity, initial velocity). they rolled along the table exactly as i would like them, and all was well. but. when i saved the maya scene and reopened it, the dice rolled differently along the table. and when i rendered the whole scene out, they rolled differently again along the table. is there any way to stop the dynamics on a an object from being that random??? and why is that the playback in maya is different from the final render?? :headbang: please please help ( i hope i have explained my problem well enough) thanks
