Chaos Group has released a free upgrade to its V-Ray for 3ds Max renderer.

The company said the update features 20-50 percent faster rendering for most scenes and introduces a new variance-based adaptive sampler (VBAS) for more uniform noise distribution, faster setup, and improved imagery for VR, VFX, and architerctural-visualisation workflows.

VBAS provides better sampling of dark areas and faster sampling of overbright areas, as well as more consistent noise detection.

Final image quality is less dependent on materials and lights settings, and it offers improved alpha channel sampling – especially in scenes with depth of field and motion blur. VBAS is enabled by default, and works in bucket and progressive rendering modes. 

In addition, V-Ray 3.3 for 3ds Max includes over 25 new features and updates, including automatic sampling of lights and materials – removing the need to set subdivisions manually, and stochastic flakes - ultra-realistic materials with sparkle effects like snow, sand, and car paints 

3.3 offers faster rendering of proxy objects and instances (above), as well as ray-traced rounded corners and smooth edges at render time, with no additional modeling – based on licensed technology from Nvidia.This offers advanced edge detection with support for concave and convex surfaces simultaneously, and works with separate objects, VRayProxy objects, displaced objects, and so on. 

There's also the new Hosek sky model to simulate more natural looking skies (above), a ground colour option for VRaySun and VRaySky and aerial perspective for efficient and realistic atmospheric depth 

The improved V-Ray Clipper with render-time booleans supports cutaways using any arbitrary mesh (below)

In addition V-Ray 3.3 offers triplanar mapping for fast, seamless textures without Uvs. It offers control over edge blending and texture parameters, including randomisation and works on procedural geometry.

The free update is available for all V-Ray 3.0 customers. Login at chaosgroup.com to download.
