Dispersion

Another Keyshot test.
This is a real fascinating tool. No matter how high you set dispersion or ray depth, you always get an instant realtime update.
Everybody, who knows Maxwell, Indigo, Fryrender or other unbiased renders, just imagine the 3D-editor window starting a render after everytime you move the camera, instantly.
Of course it cannot gather very much photons for each frame while you look around, but enough for a authentic preview with up to 60 fps (depending on the CPU) but as soon as you release the mouse, it starts improving quality at an awesome speed.
