Chaos Group announced V-Ray 1.5 RC1
CGIndia News

08, Aug, 2006 --Chaos Group is pleased to announce that the first release candidate for version 1.5 of the V-Ray rendering engine for Autodesk® 3dsmax® is now available for download. Below is a summary of the changes since the last official version.

New features

  • Support for motion blur on Particle Flow systems with both translational and rotational motion blur.
  • True instance rendering for motion blur with Dynamic default geometry for drastic reduction of memory requirements when 3d motion blur is used.
  • New Reinhard color mapping mode.
  • Sub-pixel and per-pixel color mapping modes.
  • More inteligent ray sampling to reduce noise when combining multiple blurry effects (e.g. area light illumination seen in glossy reflections etc).
  • Full floating-point output support in 3dsmax 8 and higher.
  • Support for unlimited number of render channels.
  • "Overbright" or invalid colors produced by shaders are much less likely to affect render quality.
  • Fully compatible with Autodesk® VIZ®.

  • Detail enhancement for the irradiance map. This works similar to an integrated ambient occlusion pass, but is more physically correct, rather than just producing a "dirty" effect, since it calculates correct light bouncing.
  • Adaptive path tracing mode for the light cache can concentrate samples in important areas to reduce noise in difficult situations (e.g. GI caustics) .

  • The 3dsmax Render Elements interface is now supported by V-Ray. The old G-Buffer settings have been removed. V-Ray supports nearly 30 render elements including z-depth, render ID, material ID, velocity, reflections, specular, diffuse etc.
  • VRayMtlSelect render element allows the user to extract a given material to a separate render element. This can be either a top-level V-Ray material, or a sub-material of VRayBlendMtl.
  • VRayWireColor render element allows the user to create masks with specified colors.
  • Color mapping per render element. Color mapping can be turned on or off on a per-element basis.
  • Render elements are fully supported in distributed rendering mode.

  • VRayBlendMtl material allows the layering of several different V-Ray materials. This is a lot faster than the regular 3dsmax Blend/Shellac/Composite materials and generates correct V-Ray render elements. The different layers of a VRayBlendMtl can be extracted to different render elements through the VRayMtlSelect render element.
  • VRay2SidedMtl material allows the simulation of thin translucent surfaces like paper, cloth etc.
  • VRayFastSSS material for simulating the sub-surface scattering in materials like human skin. Works best if layered with a regular diffuse/specular VRayMtl through VRayMtlBlend.
  • VRayOverrideMtl material allows the user to specify different materials for reflections/refractions/GI.

  • VRayDirt texture for simulating dirt or ambient occlusion.
  • VRaySky environment texture works either with VRaySun or regular direct lights to simulate the natural sky illumination of the Sun. For best results, use with the V-Ray physical camera.
  • VRayCompTex texture for combining textures in additional ways not available in 3dsmax (e.g. difference, division etc).
  • VRayColor texture for specifying precise floating-point RGB color values.

  • VRaySky light for simulating the natural illumination of the Sun. Works in conjunction with the VRaySky texture. For best results, use with the V-Ray physical camera.

  • VRayPhysicalCamera simulates an actual photographic camera with real-world settings.
  • VRayDomeCamera can be used to render images to be projected on hemispheric dome screens.

  • V-Ray has its own texture baking elements, which must be used instead of the standard 3dsmax ones.
  • Color mapping can be applied on a per-element basis.

  • Enhanced stability, user interface improvements.
  • sRGB option for display in 2.2 gamma space.
  • Support for pixel aspect ratio different than 1.0.

  • Direct export of V-Ray proxy meshes from MaxScript without a GUI dialog.

  • Allows the implementation of V-Ray specific materials, lights, atmospheric effects, geometric primitives, cameras etc.
  • Allows the replacement of nearly every aspect of the render engine (raycast acceleration, GI solutions, image samplers etc).
  • The V-Ray SDK is supported on the following platforms: Microsoft® Windows® NT4/2000/XP/Vista 32-bit and 64-bit, Linux, OSX 10.

  • 64-BIT READY
  • V-Ray is already running natively under 64-bit operating systems.
  • A 64-bit version for Autodesk® 3dsmax® will be available together with or shortly after the official release of 3dsmax® 9.


  • Support for IBL (image-based lighting) - VRayLight in "dome" mode can be mapped with a HDR image with optimized importance sampling for both diffuse and specular lighting.
  • The dome light can be made spherical or hemi-spherical.
  • Accurate light emission units (lumens, watts etc). For best results, use this feature with the V-Ray physical camera.
  • Separate "affect diffuse" and "affect specular" options.

  • VRayFUR
  • Added mapping for many parameters - fur direction, density etc.
  • Optimized performance.

  • VRayTOON
  • Support for including/excluding objects from the toon effect.

  • Better displacement for meshes with large triangles

  • Improved stability.
  • Render elements and G-Buffer channels are now supported in DR mode.
  • Animation is supported in DR mode.
  • Support for X-Ref'd scenes.

  • Based on a hardware lock for convenient transportation of the V-Ray licenses.
  • Floating license system for distributing the available licenses in the local area network.
