I was posing V3 on a bed and had made all the final adjustments to the fine tuning of the pose and decided to change the focal length on the main camera - when the parameters dials opened it said focal length was 0 - when i changed it weird things started to happen - this is what I got at 6. Nothing I did would change it. I had to give up, close everything down and start again. I do not seem to have the same problem again (yet), any ideas??
