--- title: "3.40 Beta 2" canonical: "https://documentation.chaos.com/space/VRHINO/116131276/3.40%20Beta%202" format: markdown --- *Beta 2 (3.40.27197)* **Date** – November 1, 2016 **Download** – [Build 3.4 Beta 2](https://download.chaosgroup.com/?architecture=x64&product=47&platform=51)    ## **New Features** ** ** --- ### **General** - A V-Ray for Rhino toolbar provides quick access to common V-Ray features - New V-Ray for Rhino User Interface - V-Ray Swarm (previously Distributed Rendering – OSX as a render node not supported) - New progressive image sampler - Extensive optimizations for render speed, especially when using brute force GI - Implemented the V-Ray Denoiser - The Intel Embree library is now integrated into the V-Ray core for static and motion-blurred geometry - New streamlined installer - Faster rendering of dynamic meshes, instances and VRayProxy objects - Dynamic Bucket splitting - Implemented probabilistic lighting and controls - Implemented .vrscene export - Implemented **Get View Aspect** function in UI so users can import the exact screen aspect ratio by using the **Get View Aspect** function inside the Quality Quick Settings - Variance Base Adaptive Sampler (VBAS) for better noise control in dark areas and faster sampling in over-bright areas - Implemented **Show Safe Frames** in UI so users can now frame a view in Rhino to see the exact proportions in the scene rendering using the **Show Safe frames** function inside the Quality Quick Settings - GGX BRDF Support adds the Generalized Trowbridge-Reitz BRDF. With finer highlight controls, it's ideal for metals and reflective surfaces. - Implemented V-Ray **1-Click** 6:1 Stereoscopic Cube render. A hard-coded way of rendering a dual camera stereoscopic 6:1 image for use with preferred VR headsets with a single click.Implemented ready-made V-Ray material library. Choose from a variety of (temporary until new library is created) ready-made materials. - Light leaking prevention in Light Cache - Improved Speed ### **Materials General** - Material Quick Setting - Drag and drop material layers for easy alignment - Material Browser System - Material Presets ### New Materials - V-Ray Fast SSS material - V-Ray Blend Material - V-Ray Bump Material - Improved Two-sided material - Microfacet GTR/GGX BRDF - V-Ray Hair Material - V-Ray Scanned Material - V-Ray Stochastic Material - V-Ray Override Material - V-Ray Car Paint material ### Texture Support - V-Ray Curvature - V-Ray Edges Tex - V-Ray MultiSubTex - V-Ray Triplanar mapping texture - V-Ray Angle Blend - V-Ray Composite - Wireframe rendering and Round corners using V-Ray Edges Tex - Ability to map the V-Ray Dirt Radius - New procedural textures UI arrangement - Ability to copy and paste and drag and drop texture maps - Updated and newly Implemented Textures in the procedural texture editor - Falloff – Emulates the Max Falloff texture - Fresnel – Emulates the Max Falloff texture - Noise – Emulates the Max Falloff texture - Noise Legacy – 2.0 Legacy Texture - Ability to map VRayDirt radius ###  V-Ray RT General - Speed improvement - Support for the VRayClipper objects - Support for VRayDirt, VRayFastSSS2 and VRayCarpaint - Added support for VRayMtl anisotropy - Added support for VRayFur - Added support for mapped IOR of VRayMtl - Support for using light cache for GPU rendering - Better support for AMD hardware - Support for infinite plane ### V-Ray RT GPU CUDA - Support for the NVIDIA Maxwell GPU architecture - Support for the NVIDIA Pascal GPU architecture - Implemented QMC sampling for CUDA engine - Implemented coherent tracing (may improve rendering performance) - QMC sampling using NVIDIA CUDA (resolves noise faster) - Support for coherent tracing (may improve rendering performance) - Support for Displacement - Anisotropic highlights - Support for V-Ray Fur - Support for layered material transparency ### V-Ray Stereoscopic | VRayStereoscopic - Simple 1-Click rendering for Stereoscopic 6:1 images ### V-Ray Proxy | VRayProxy - Support for Alembic 1.5 - Ability to specify starting path in Alembic files ### Environmental Effects - Aerial perspective ### V-Ray Sun & Sky | VRaySun / VRaySky - New sky model (Hosek et al) - Added ground color parameter ### V-Ray Mesh Light | VRayMeshLight - Implemented Mesh Lights ### Rectangle Light - Implemented Shape function in UI to allow change from rectangular to ellipse - Faster sampling calculation for area lights ### Spot Light - Support for bitmap and texture projection ### Sphere Light - Support for bitmap and texture projection ### V-Ray Dome Light | VRayDomeLight - Implemented function where when you add a dome light to your scene you can actually control its direction by rotating the in scene object ### V-Ray Clipper | VRayClipper - Implemented V-Ray Clipper ### V-Ray Fur | VRayFur - Implemented V-Ray Fur - Implemented options for hair curling - Faster rendering (accelerated by Embree) ### V-Ray Render Elements - Added support for ExtraTexChannel – Produces a render with a single texture applied to all objects in the scene. The texture applied to the scene can be a bitmap or a procedural texture such as V-Ray Dirt or V-Ray Curvature. - Added support for custom ZDepthChannel – Provides information about each object's distance from the camera in the current view. Objects between the furthest and nearest points are rendered in varying shades of gray. - Added support for Denoiser – The V-Ray Denoiser takes an existing render and applies a denoising operation to it after the image is completely rendered out via normal means. The denoising operation detects areas where noise is present and smooths them out. ### V-Ray Frame Buffer - Can be zoomed in/out with the regular +/-/* keys (useful for remote access from mobile devices) - Option to automatically save each render in the history (enabled from the VFB history options dialog) - New color corrections - contrast, HSL, color balance - Deleting an image from the VFB history now sends it to the Recycle Bin - Users no longer need to turn on bloom and glare before render a scene to use the effect - New dockable history and color correction tools - New Reinhard highlight burn color correction - Save multi-channel OpenEXR and. vrimg files directly from VFB - New option for loading files into VFB as background images for post processing - Load color corrections - Save LUT files
