Well, in that case, you should definitely stick to rendering in P6. I bought C5 Pro last February because of the trouble Poser was giving me regarding texture memory. I had a great many scenes that I couldn't render regardless of what size I set the bucket to. I've had far fewer such problems with C5, although it has a texture memory limit too. It's just higher. Also, I find C5's rendering quality to be superior. Your mileage may vary.  I haven't hit P7's texture memory limit, yet, but I've only been using it for a couple of weeks. I had one scene that grossly exceeded the texture memory of BOTH C5 and P7. I was finally able to render it in C5 by exporting a large group of the scene props from P7 as .obj's, and importing them into the scene in C5. I think that worked because obj material files don't store multiple copies of the same texture map if it's used by 100 copies of the same prop. Anyway, here's the rendering of the same scene done in P7. With raytracing set to 2 bounces and shadows on. The toon on my site was done in C5 with raytracing set to 8 bounces. Pixel accuracy set to 0.5, sharpness set to 100%, and shadow accuracy set to 1 pixel.
