I figured. I've seen this problem with Maya and nVidia Quadro/FX/whatever they are called cards. There is probably a fix for it but I've never bothered searching it out.
The funny thing about films is that the visual FX keep getting better and better yet the narrative and characters seem to dwell in some kind of childish quagmire.
VFS is the Vancouver Film School, www.vfs.com I'm using about 2 metal working tools and a brush with some alcohol to smoothen things out here and there.
