Been playing with this for the past hour and no major problems at the minute. I have come across the dreaded 'not enough memory' issues when rendering though - but I'll accept that CL are trying to fix this at the minute. Not impressed with Jessi at all, don't think there will be many photorealistic renders done with her... As for the book, it says its available now at $25 at the Curious Labs Site? Must go have a look.
