@TheCastellan, I haven’t tried it, but there’s a notebook computer at Renderosity: http://www.renderosity.com/mod/freestuff/details.php?item_id=16627 . There was a free MacBook I got somewhere, but don’t know where or if it’s still free. If you have PoserWorld access, check there (but I don’t think I got it there.) I’ve seen others around, along with PDAs if you are looking for something smaller.
@Kerya, @chohole, and @robkelk: Thanks for the links, and the search term! I’m checking through the links now.
Any idea if commercial renders using 3D warehouse buildings are allowed? I’ve only looked at a few, they seem kind of hit-or-miss for quality, but I’ve found at least one so far that will work great for a background cityscape, hopefully there will be a lot more.
The radio is perfect. The first link right after “Maybe for background use”, http://www.3dcadbrowser.com/download.aspx?3dmodel=1650 , would also have been good, although it says I need a different kind of account to download that one.
