BLENDER
This actually started as a real house project when purchasing a new home. I needed a wall piece to adorn the living room space and therefore I took to designing the structure to be provided to the contractor to help visualize the project.
The scene was rendered in Cycles but I had to increase the sampling to about 100 in order to eliminate most of the noise (this is a big issue with Cycles). It too several hours to render the scene though.
Sampling: 100
Light Paths: Full Global Ilumination
Performance: Fixed, Cache BVH - On, Persistent Images - On
