Big helper for stability - small texture sizes! Can't say this enough and I want to smack some of those skin texture people and set texture people. 3000x3000 for the textures for a wall is ABSURD! Rendering that is like trying to flush 3 whole rolls of toilet paper at once. A 3000x3000 texture unpacks to 36,000,000 give 32 bit color depth. And heck I'm just being nice here. I don't even know for sure if Poser duplicates these resources when passing them to firefly plus it maybe constructing the final texture for render use from shader node operations so that's another duplciate right there. Having seperate lipstick, makeup etc add ons that are 3000x3000 each is beyond absurd. One face with seperate lipstick, face and eyes at 3000x3000 each comes to 96 megs just for a face! Irrregardless of hard drive packing, the texture is mostly likely decompressed and left in full size in memory. Also people don't realize that unless your final render ends up with the same textile resolution you ain't benefiting from enormous textures. A 3000x3000 texture render in a 800x600 pic is not going to show any more detail than a 1024x1024 equivalent. You don't get half a pixel or quarter pixel clarity. Anti aliasing occurs post render when the pixels are averaged. If I have low texture sizes I can render almost indefinitly and thats with 3 Vicky 2s, 6 Mike 2s, several Dystopia blocks, several buildings and several vehicles all in one scene.
