Hi,
Solution?
Keyshot 3.1.48
The scene - Teapots. The environment - hdri-location_urban_4k. Material of teapots - diffuse.
W7 x64
i5-2500K
GTX-570, driver 296.10 (last)
No error as such, and hardware just fine. Just note that diffuse material does not reflect the environment. It's just "flat". Switch material to something else, like paint or metal. To really see how the enviroment works use "chrome".

I changed material (now paint) and shadows are bad.
