Thanks.
I honestly don't remember how long it took. I'm sure I knew back when I did it but that was many beers ago.
Carrara Pro 6 has a pretty fast render engine and so most of these shots didn't take that long to render. They probably took more time to set up. I know the bridge shots took a while to set up because I had to covnert the bridge to Daz/Poser friendly environment and the shots you see of it are my 'lighting tests'.
I'm still working on getting the lighting where I want it.
The starship tests were specular mapping, running lights and volumetric clouds.
I've been asked a few times how long some of the scenes take and so I think I might start logging down that soft of info.
