Render times... Since I upgraded recently from Win98 to WinXP, without changing the hardware, I've maybe got a feel for one or two details on this. There seem to be two distinct problems with similar symptoms. Both show as very slow, or no, progress at the loading objects stage of the render, which can happen several times if you use shadowmaps. The total halt version (I'd call an overnight run with no results a total halt) seems to have been fixed by the switch to WinXP. I still see very slow processing which may be the fragmented group/material problem, perhaps more often now. Since WinXP uses more RAM for the OS, I'm inclined to think virtual memory is one of the keys. The last instance I hit used DAZ's SP3 and V3; just the two figures each with only one or two INJ morphs loaded. Incidentally, this would be something that would be more likely to show up with a triangulated mesh. Right?
