Background plate for a film I'm working on. The actor will be sitting on the edge of a desk in the foreground. This is a Blender render (as opposed to a cycles render). I'm fairly new at Blender and still figuring things out. I ran into some weirdness with my window frame reflections of the rock wall (way over-emphasized the bump map, but just where the sun lit) when I positioned a sun to cast window shapes onto the carpet. I wound up placing a planes as a "ceiling" with window shapes cut out, and put a single light source directly above. Presto! No bump problems.
The background image is stock, and is for now a place-holder; I'll have to replace it with one that matches the direction of the sun as I've established it.
