Many thanks to all...I'm a newbie and there is lots to learn. My goal is to produce Poser images that I can then work on in Photoshop where I'm trying to mix and match 3D and digital photographs. My editor likes the idea but insists on the final image being 50MB (without interpolation). The pagefile workaround sounds great. Dizzie...the 49MB render took less than five minutes. Took a bit longer in trueSpace.
