Hi,
in a short I'm working on there's a couple of scenes where I need smoke to be sprayed out of a graffiti-like spraycan. I'v set up my particle system in a way that the smoke grows over particle age and is affected by a bit of drag and wind, no problems there.
I'm kinda stuck in the way it should be rendered... atm. I'm using camera-facing rectangles with a smoke-material applied to it. (the smoke material is a couple of animated noise maps in diffuse and opacity channels)
now, first and for all, these things tend to render for ages! (camera is placed INSIDE the smoke particles, facing the emitter by the way)
and secondly, I really dont like the 'puffe little clouds' in the beginning.
So, does anybody has any knowledge to share regarding smoke-rendering and the materials I should use. Also, what's the key to remove the 'puffy' cloud sphere look?
thanks in advance,
Foane
