I'm working on a new worflow to get the best from Modo in less time, just using "11/12" render passes then composited in Photoshop at 32bits.
It's a rural house in Farnetella, Toscana (Tuscany) and I love these places.
Actually I'm not sure about the illumination 'cause I'm working on a LCD "non professional" monitor, but I'll calibrate the levels for a final version on my trustworthy CRT.
All I can say is that working in render passes with Modo is absolutely functional. I did a lot of test to correctly match the final render and it is very hard to composit 32bits render passes in Photoshop CS3 (bad program, BAD PROGRAM!). After this, I will composit my file with a better program as After Effects.
