Render most scenes up to 20-50% faster with V-Ray 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 Features
• Ray Traced Rounded Corners – for perfectly smooth edges at render time
• New Sky Model and Aerial Perspective – for realistic natural-looking environments
• Triplanar Mapping – for simple, UV-less textures
• Improved V-Ray Clipper with Render-time Booleans – for cutaways using any arbitrary mesh
• Stochastic Flakes – for more realistic materials like snow, sand, and car paints
Many features have been updated as well, including better global illumination and GPU rendering with V-Ray RT.
