Beautiful.

I agree it is a little noisy, especially in the reflection of the one on top. How did you make that material?

Great, maybe someone could render it a little longer for you to reduce the noise.

I just downloaded indigo and the exporter and set up a simple scene. I've tried using other files with indigo and they worked fine. All of my exported files won't work though. I have been changing the names of files to ior_test, since I don't want to mess with windows command line.
