Corona Renderer delivers high quality, physically-based shading in production rendering.
All its features are tightly integrated into Autodesk 3ds Max.
New Sky Model has better overall tint to the lighting in daytime, but most importantly supports the sun being below the horizon (as low as -2.85 degrees, or roughly 5.4 sun diameters) for dawn/twilight
Randomized tiling in the UvwRandomizer lets you avoid the “repeating pattern” look that even seamless textures have
New Adaptive Environment Sampler removes the need for Portals, saving you the time (and pain!) of setting those up, while giving more accurate results
New Lens Effects give you vastly more control over bloom & glare
Material Library update with 78 new materials
New Masking options that work in reflections and refractions giving you greater control in post
Support for Phoenix FD Foam so you can take full advantage of Phoenix FD water simulations
