Here is a sci fi hallway that is part of a personal project that I am working on. For the most part, this is my work except for 3 items. The HAL-9000 unit mounted in the wall I downloaded from this site. I give credit to elkid for that. The chairs I also downleaded off this site as well and I give credit to sensenku for that. I have made a small texture change with the chair though. As far as the keyboards that sit at each terminal, I downloaded them from this site as well and give credit to fender750 for that. Other than that, the rest of the model is my work.
Did you follow the Blender Guru tutorial for some of this?
