Chaos Group就在不久之前推出了V-Ray V3.30 3ds Max 2009 – 2016。这是一个免费的升级可以让你在3ds Max里使用V-Ray提高20-50%效率更快的渲染场景，介绍了最新的自适应采样方差（VBAS），能使渲染时噪点分布更均匀，更快速的设置VFX、VR技术等提高工作流程等。
重要更新：
基于方差的自适应采样（Variance-Based Adaptive Sampling，简称VBAS）
过亮过爆或暗区都将获得更快更好的采样
更一致优化的噪点检测
最终图像质量是不依赖于材质和灯光设置的
改进的alpha通道的采样，尤其在渲染场景的景深和运动模糊时
可更稳定的工作于大型巨量和渐进的场景渲染模式
此外，V-Ray 3.3 for 3ds Max中包括25多个新功能和更新。
新功能包括：
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 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
Stochastic Flakes
超写实的材质，如雪，沙砾，金属，车漆等。
更新功能包括：
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-Faster rendering of proxy objects and instances
Geometry
-Faster rendering of proxy objects and instances
