Bidir works alright if you also have high absorption.
These are based on http://graphics.ucsd.edu/~henrik/papers ... roperties/
Phase function was kept under 0.8 as the material gets substantially darker above that. I don't know if this is a bug or...?

I can upload it to the mat db once these guys figure out if they want an updated preview scene...

Awesome milk! Please share. If you are having trouble with the MDB, could you post the text from the IGM file?
Re: Milk (regular) optimized
The attack vector stuff was for forum attachments.
After rendering for a while in the preview scene it explodes into some colored noise light party.

Re: Milk (regular) optimized
Is it right to use a gamma of 1 for all those parameters ? TBH I can't answer that one.

Re: Milk (regular) optimized
That's what looks best, and Ono said somewhere that you should use 1 when using measured data which this was based on.
Also some posts about it at http://www.indigorenderer.com/forum/vie ... 3&start=60
