Chaos Group updates core algorithm in V-Ray 3.3 for 3ds Max

Variance-based adaptive sampling makes renders easier to predict and control.

Chaos Group has released a free upgrade to its V-Ray add-in rendering toolkit for Autodesk 3ds Max. Chaos Group says the update provides 20%-50% 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 arch-viz workflows.

By default, variance-based adaptive sampling will be on in the new update. Chaos Group says VBAS provides: 

  • Better sampling of dark areas and faster sampling of overbright areas 
  • More consistent noise detection 
  • Final image quality is less dependent on materials and lights settings 
  • Improved alpha channel sampling –?especially in scenes with depth of field and motion blur
  • Works in bucket and progressive rendering modes 

Other new features in this update:

New global defaults: Automatic sampling of lights and materials – removing the need to set subdivisions manually 

Ray traced rounded corners:

  • Perfectly smooth edges at render time with no additional modeling – based on licensed technology from Nvidia 
  • Advanced edge detection with support for concave and convex surfaces simultaneously  (see video)
  • Works with separate objects, VRayProxy objects, displaced objects, etc. 

New sky model and aerial perspective: 

  • Hosek sky model to simulate more natural looking skies (see video)
  • Ground color option for VRaySun and VRaySky 
  • Aerial perspective for efficient and realistic atmospheric depth 

Triplanar mapping: 

  • Fast, seamless textures without UVs 
  • Control over edge blending and texture parameters, including randomization 
  • Works on procedural geometry 

Improved V-Ray clipper with render-time booleans: Supports cutaways using any arbitrary mesh (see cake illustrations and video) 

Stochastic flakes: Ultra-realistic materials with sparkle effects like snow, sand, and car paints (see video)
