Hi. Decided to try Corona Renderer... Excellent speed and quality "out of the box." To the materials need to get used to. Especially defies understanding of parameter Fresnel IOR. For me, the benchmark is Maxwell Render Material. Would be great see the same in Corona... :)
In this scene I used Corona Sun/Sky and default render settings. Depth of Field and Motion Blur from Corona Renderer. Post: MagicBullets Looks (ColorCorrection and glow)

Models of crystals for MultiScatter.
