I'm afraid it won't work as expected with scanline or ART as they have not got translucency and they don't support transparent shadows. Also no GI at the moment. You might get similar results using some tricks. I posted few days ago some useful tips and tutorials about traditional lighting or 'faking GI' in this thread:
http://www.anim8or.com/smf/index.php?topic=3473.0 I believe that ability to light the scene in classical way isn't useless, especially in architecture and animation because traditional lighting is way faster to calculate than GI. Just look at the entries of 'Challenge #4: Indoor Render'
http://www.anim8or.com/smf/index.php?topic=2290.0 or 'Challenge #14: Sports equipment' $imon's entry
http://www.anim8or.com/smf/index.php?topic=3238.msg22812#msg22812 All of these were made with scanline and/or ART.
If you want an instant solution (natural looking render, not very 'instant' considering rendertime) I'd suggest to try unbiased renderer such as Kerkythea
http://www.kerkythea.net/joomla/ or LuxRender
http://www.luxrender.net/ . Basically you export your objects as *.obj and import them directly into Kerky or to Blender for export into Lux. But don't expect fast rendering and very artistic effects without creative use of light and changing defaults, actually the lighting will look just OK and 'correct' with minimal effort
If you'd like to make your rendering more personal I'd still encourage you to follow the tuts about how to setup your lights by hand.
Whatever path you choose I'll be looking forward to see the results
Cheers!
