I put together a living room scene from various models found around the net. I created the room space and setup the lighting and environment. After lengthy discussions on the Lux forum about how to setup lighting “correctly” I am finally gaining an understanding of this light accurate renderer works.
In this scene, there are only two lights, the environment and the recessed light in the background that is lighting the glass vases in the small alcove.
This image is the result of 4,300 samples that took 13 hours to calculate.
