Image of a catacomb I had forgotten on my hard drive, I wanted to finish. Searching on Internet I found a lot of images of catacombs, I don't remember what I was looking for, but I found some really cool images.
Is made in 3Dmax/MentalRay for basic shapes and light using one texture, Zbrush for the columns and Photoshop for painting over, basically a exercise of mixing techniques.
I will post the 3D geometry and the render, I think is a very nice technique if you want to achieve perspectives and lines more believable.
I hope you like it.
