We've been working hard to produce better quality results in less time. Serious performance improvements in our core rendering code mean that Indigo 2.2 is at least 2 times faster than Indigo 2.0.
Faster environment mapping
Environment map sampling has been made much more intelligent, resulting in speed-ups of 10 times or more when using environment maps.
Improved Subsurface Scattering
Subsurface scattering (used for skin, candles and rubbery materials) has been improved to render faster and with less noise.
Faster Tone Mapping
Tonemapping is now fully multi-threaded making it up to 7x faster than in Indigo 2.0. Aperture Diffraction has also been optimized allowing for more rapid tweaking of the scene's mood.
New Material Editor
We built the Indigo Material Editor as part of our effort to make the technical features of Indigo accessible to more people. It lets you modify all the aspects of an Indigo material in a visual way, and compare before and after renders. For new users, or experienced Indigo users, the material editor lets you explore the physical properties of materials and then use those materials in your scenes. You can also browse, download materials from, and upload materials to the Indigo material database from inside the Indigo Material Editor.
User Interface Improvements
We've made a host of small improvements to the Indigo GUI to make it more intuitive and responsive.
Absorption Layer Transmittance
Absorption Layer Transmittance is a new feature added to the Indigo Material Medium, great for stained glass!
