I am getting reALLY strange results when network rendering via net queue EVEN when only doing it on one machine. For instance to render the morph duck off the WCT-CD, if I use net queue, every couple of frames is rendered dark, as if the lights were on extra low, then after a while, every frame becomes dark. The same thing happens if I do it across a few machines, some frames come out 'dark' looking. It would not appear to be a file access problem as it happens when using just one machine to do the render. We are going to be demonstrating the networking capabilities at a show next week, but it don't look good at the moment. Any ideas???? Thanx…Peter
