Hi Phil, I have never tried importing RW textures into Artlantis, but I know there's a way to extract RW texture images... so it should be viable.
As far as lights, I don't think they export into Artlantis.
Sorry couldn't be more helpful...
How r u liking Artlantis 5? I have version 3, but considering upgrading. I only use Artlantis very sporadically, since I'm usually satisfied with RW's quality, but always nice to have the option to have a better rendering. Have u tried the Maxwell rendering engine?
cheers
Carlos
