I am still basically a newbe to Poser and here is how I deal with the RAM woes. I have 1GB of ram with my virtual memory (paging file) set to 1.5 - 3GB and sometimes I still have trouble. 1. Disc Cleanup before almost every production render. 2. Defrag regularly. 3. Kill my antivirus program and as many of its processes as I can. 4. Using the Material Room in P5 remove any unnecessary/unseen skin textures, etc. 5. Make any hidden geometry invisible by unchecking the "visible" property. 6. Use a dial cleaner on the file before render if you have multiple DAZ characters in it. 7. Delete any scenery that doesnt end up in my final camera angle. 8. If all else fails, render in "layers" by doing multiple renders, each being only a part of the final product and compile in Photoshop. Hope that laundry list helps someone out.
