Ok i haven't worked on these much yet but i tried to make a decent job of the textures. The texture map is 3000 x 3000 pixels so theres plenty of detail there, i also created a high res bumpmap for it.
At the moment this is just the plain landscape with no other objects on. The two render below were done using firstly the Art renderer and then the second with the scanline renderer. The art renderer only took a min or two but the scanline took about 2 hours! You can really see the improvments made on render time with the art renderer! Resulting images look virtually the same!
I'll upload these and some more images to the website soon when i get a chance to update it. www.test-chamber.110mb.com
