Since P5 is a memory hog and you are on a smaller machine , you might look at the size of your texture maps. Try reducing and still keep the quality you want. If any part of the body is covered with clothing, hide it. Finally, before rendering, save the file then run Dial Cleaner, you should have it if you bought M3 or get it at Daz, free archive. That will help cut down the size of the file by removing unused V3 or other inj figures channels.

I must remember to remember what it was I had to remember.
