vray 3.3 – rendering fotorealistici

V-Ray_logoVray 3.3

ChaosGroup ha ufficialmente rilasciato la versione 3.3 di VRay per Autodesk 3ds Max.

La nuova versione, scaricabile gratuitamente dai possessori di una licenza 3.x del motore di rendering, oltre a risolvere alcuni bug minori sopravvissuti alle precedenti release, introduce diverse nuove features.

Novità in cui spicca il sensibile abbattimento dei tempi di rendering, valutabile nell’ordine del 20-50%, grazie ad un’ulteriore ottimizzazione degli algoritmi di calcolo, sempre meno dipendenti dai settaggi di luci e materiali proprietari.

Un risultato incredibile, se si pensa ai progressi sviluppati con le precedenti service pack di V-Ray.

A seguire, l’elenco delle note ufficiali, riportate dal sito ufficiale di V-Ray.

Chaos Group has released service pack 3 for VRay for 3DS Max, bringing a long list of new features and improvements: 

  • Render most scenes up to 20-50% faster with VRay 3.3 for 3ds Max! V-Ray 3.3 for 3ds Max introduces new variance-based adaptive sampling for quick setup, uniform noise distribution, and higher quality images – with less dependence on settings for lights and materials.

Variance-based adaptive sampler (VBAS)

  • 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 VRay 3.3 for 3ds Max features include:​

New Global Defaults

  • Variance-based adaptive sampler enabled by default
  • 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
  • Works with separate objects, VRayProxy objects, displaced objects etc.

New Sky Model and Aerial Perspective

  • Hosek sky model to simulate more natural looking skies
  • Ground color option for VRay Sun and VRay Sky
  • 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

Stochastic Flakes

  • Ultra-realistic materials with sparkle effects like snow, sand, and car paints

Updated Features​

Global Illumination

  • More robust handling of reflective GI caustics, better light propagation, and more natural illumination of interior scenes
  • Distributed light cache for faster calculations with distributed rendering

GPU Rendering

  • More texture nodes – MultiTexture, VRayMultiSubTex, ColorCorrection etc.
  • Proxy objects with hair and particles
  • VRayFur and VRayPlane objects
  • Light include/exclude lists

Progressive Sampler

  • Dynamic noise threshold leads to more uniform noise distribution
  • Improved sub-pixel filtering
  • Improved CPU utilization

Volume Rendering

  • Faster volume rendering with probabilistic sampling

Geometry

  • Faster rendering of proxy objects and instances
  • Faster rendering with Forest Pack Pro

V-Ray Frame Buffer

  • Compare V-Ray settings
  • Load color corrections
  • Save LUT files
