Why Liquids render so dark inside glass with BidrPT

Post by Googog Mogog » Thu Apr 14, 2011 2:32 am

Hello,
Another of my problem why materials like liquids or sss render so dark with Bidr Path tracing method inside glass,These liquids inside glass or sss materials render so good with normal path tracing method. Here i am giving u a scene with glass and milk plus a tube light inside glass and milk and a studio light for environment set the (White light layer to somewhat 75.000) to get better environment light.

The precedence of the glass need to be at least 1 higher then the fluid!
Last page of Indigo Manual shows how to setup a fluid in Glass scene, check it out :)

SSS is scale related, take care to export your scene in life size scale.
A 10m high glass filed with red wine isn't transparent anymore ;)

You have to do the math by your own mate, if your glass is 100cm tall then downsize it or switch to mm.
