This is one of 5 architectural renderings I created for a recent animation project. All done with Blender and Cycles. I also used GIMP and Inkscape to create some of the textures.
This particular image was 1000 samples and took just over 5 hours rendering on with an i7. it unfortunately required too much memory for my gpu to handle.
The animation was rendered in Cycles, features dynamic paint and I even used Freestyle to create an animated texture. The audio was edited in Audacity and mastered with Acoustica Basic.
