Hi I am trying a new approach to an animation and would like to do a sort of film noir type scene with fog or maybe rain. I have the fog particle in place but it doesnt start at the beginning of my scene but appears quiet far into it. Can anyone point me in the right direction to either edit the start of my fog particle or a good tutorial on how to adjust my particles so it starts at the beginning of my scene. I may want to use rain in the future and i have tried that too and that has the same problem. 

Many thanks

Woody
