Scatter fog workflow?

[mr furious]

Hey Everyone,

I've been messing around with scatter fog. I need to do a search light type thing, but I can't seem to get a high enough quality without render times skyrocketing because i have to crank up subdivs.

what is everyone's workflow for this? constraining the scatter fog to geo container seems to help a little bit. What type of AA are you using. Right now I have to resort back to MR for volumetric effects because the render time are very quick.

I want to keep everything in vray...but the cost of the volumetrics are killing me.

any help is appreciated.

Andy

bueller...... anyone......

adaptive dmc sampling with threshold at .010.
Max 4 subdivs
AA Area @ 1.5
8 subdivs on the fog itself, sometimes a bit more

As for the fog parameters itself, this is handy reference:

Nothing special!

that makes sense... i was using scatter fog vs env fog.... that works much better.. try and do the same thing with scatter fog...and you'll never get a clean result.

thanks
