cloud cover .... Ozone ?

[cdavis]

Hi,

I was wondering if anyone has any experiences rendering Ozone clouds in Vray ( 3.x) beta ? . I'm looking for the quickest way to generate cloud cover that can be affected by the physical sun/sky to make a time-lapse sequence, that looks good quality ?

Any tips on clouds be appreciated ?

Cheers
Chris

It works well, but it's incredibly slow. render out a hdr sequence and use that for your scene if you're going to do it at all. they have a demo which works, just is low res and has a watermark. so you can finish it, decide if you like it then buy the software and press render.
personally i'd try and shoot it, overlay it on the sky with a comptex, project it onto planes for reflection etc.

I have no experience with maya whatsoever and don't know what is available. My two cents about ozone though. Like Neilg said. It's INCREDIBLY slow. I don't know if Maya has access to vray environment fog but you could try this: http://vray.info/tutorials/vrayenvfogclouds/

Its quite fast if you render it using adaptive subdivision -xx -xx values. its clouds they can be smooth noisy etc etc so just de noise in ps. You can get away with a lot and get fast renders.

Or I was using it wrong. Because my LC took 10 min and there was nothing in my scene

Definitely seems like a thing to render a second pass for - as everyone has said it gets very nasty time wise if you use anti aliasing settings that it doesn't like and if you're using settings to get high quality results on your 3dsmax scene, rendering your ozone stuff at the same time with the same settings could be nasty.
