*"Now rendering complex scenes with 5 or 6 generation 4 figures.*"

 I don't call that complex at all, for me that's a normal scenes. I can easily do that on my 2Gb machine..... actually I've gone as far as 24 fully dressed and textures M3/V3 figures on my machine. Of course, it takes a lot of fine tuning the pc, but once you do Poser can handle amazing complex scenes.

My regular scenes are 4-6 figures with a complete enviroment around them, that may be a city, furnitured house or landscaep like a forest. Poser has no problem handling and rendering them at 2000x1871, at times I've still got half of my memory left over.

The attached scene is what I do call a regular scene, nothing complex at all. Each figure is morphed and uses a different body texture, clothes in this scene are all the same, but it varies per scene. I had to downsize the image to be able to attach it, original it's 2000x1871 pixels.

Artwork and 3DToons items, create the perfect place for you toon and other figures!
