When using networked rendering, it seems as if the tranparency maps that Poser uses on things like hair and feathers can get 'lost' in some frames, so you get an odd strobing effect. On the test, it was only the tailfeathers that were doing it; the wing primaries transmaps were stable. I just got the newest release of 4.12 ( I did get it the first day, so that may be fixed), so I get to try it again... Oh, as a heads up, I just stopped in at Phoul's site ( www.belino.net ), and he's got the tutorials section down for upgrading. Hopefully he's going to spill more of his secrets... :)
