Nice! To get the same noise level I would have to render it like for a week or so on my old AMD. 8)

Well..what can i say, you have to use the same technique that is used in this example scene. For example make a large box. Put everything inside this box. Give the box an SSS material with the precedence of 2. Every medium that is inside that box must have precedence higher than 2. Put the camera outside the box. Render.

It's not so much related to exporter. The Indigo Manual is a really good place to get help. I recommend to read it. :wink:

I think you can already use participating media with sunlight.
You just have to work around the current limitations - for example the camera can't be in the fog (or whatever) medium.
