Luxion has updated its ultra-fast ray-trace rendering program, KeyShot 2, to version 2.1 for Mac and PC, bringing new features and improvements to existing ones. Among the many changes: additional support for a wider array of import formats; an all-new labelling system; an array of new and reworked materials; a new Performance Mode that turns off extraneous items (like ground shadows) to save processing power; an improved Undo stack; different UI color schemes; specular labels with control over reflectivity; real time Bloom, glossy reflections and ground shadow color
