Hi I have made a 30 second long animation that includes a douzaine of emitters on top of the normal animation. My prblem is that it takes a VERY long time to play it and after a while, particles start shooting all over the place (even though it's not supoose to). I really need to reduce this processing time ... Either way, I think my problem is that there are a lot of unnecessary instored by maya, so I was wondering if you guys/girls could give me pointers on how to delete unneeded information (such as edit --> delete all by types --> static chanels) and other forms of methods to overcome this problem. Thank you very much, Alex
