I am using vue 9 xstream.

Thanks. I have looked a  lot on daz. I have some of the seriously real textures, but am not sure they are as good as some of the ecosytem types in Vue. I think also, that the skies are more realistic in vue. I guess I need to get better at making them in Bryce.

Thanks for the info. The long render times are when I render 3200 X 2400 pixels. the preview renders are a few seconds. So, I guess it is the other factors you outlined.

I have an x6 1035t system with 16 gb ram and have very long render times in Vue with fairly simple scenes. The task manager shows all cpus at 100% during renders. Render times are long (over 24 hours) with 3200 X 2400 high res renders. I think my video card may be a problem just using the program as it is a radeon 5750, and I understand that you are better off with nvidia.
