Our milestone edition 1.3 is now available and brings some powerful new features along with substantial improvements. Presto runs now on both GPU and CPU; using NVidia CUDA and Intel Embree, it brings Thea's top quality in the shortest render times. Presto is quite more sophisticated with improved sampling techniques, instancing, subsurface scattering and volumetrics support. A new, more accurate, physical sky model; camera z-clipping; automatic updates; we are the first to introduce "micro roughness" to simulate the phenomenon of roughness decrease at shallow angles. Many bug fixes and other improvements make it an opportunity that you just can't miss!
