give volumetrics a geometry?
 

I am trying to give volumetrics a geometry. I.e., i am trying to show where the light of a fogged spotlight falls, but not just in a render, in the actual maya programme. I've been messing around with fluid mechanics as I know it can be done this way, but this did not turn out well. Does ANYONE have ANY ideas, as i am really really really not getting anywhere. I think it might be possible to add geometry rto a render afterwards in premier? Is this possible. if so how? any help would be very much appreciated. Rachel. :confused:
