OK, I have see The Bug, and it is The Enemy. Way too easy to replicate. I loaded the DAZ Woodland Playset, plopped the hi-res Winter Queen into it, and used the highest auto render settings. Got the memory error message (and a totally erroneous message about missing textures) pretty quickly. Went back and tried again at my default manual settings (3000MB max texture size, three raytrace bounces ... no shadows in this case as I'm using IBL/AO) it's rendering now with no problem (and no missing textures, LOL.) This scene is WAY too simple to cause memory problems ... not even half of what xeno suggests trying. I get it now. This isn't a problem for basic renders that I can share online or view on a computer, but I'm doing more illustrations for a magazine these days, and will need to render at very high quality and sizes. I saw the message at CL indicating that they know there's a problem. Let's hope the wait for a fix won't take too long, this isn't acceptable for some rendering contingencies. Otherwise, I'm a happy Poser 6 camper, fer sure.
