Quote - I remember a pdf tutorial, but it never worked when I tried it...

The tutorial Casette remembers is Poser Soft Bodies by RajDArge - it's in the tutorial section here. Your first hurdle will be getting the PDF to open. I found that although Adobe Acrobat wouldn't work, one of the alternative progs like Sumatra PDF would do it. I still haven't tried this yet. The method seems complex, and I don't understand the reasoning behind some of the steps. Maybe if I had the time to work through it it would become clear. :) ... Here's a crazy thought, off the top of me 'ead. What happens if you plug AO into displacement, with an offset to make it run negative?
