V-Ray SP4 is out!

Build 3.40.01 (official) (31 May 2016)
==============

New features:
(*) V-Ray: Add support for 3ds Max 2017 including:
- Initial support for the new Physical Material;

(*) VRayDenoiser: Implement a new render element that contains a denoised version of the image:
- The denoiser can take advantage of hardware acceleration;
- The denoised result can be adjusted after a render is complete;
- The denoised result is updated periodically during progressive rendering;
- The render elements required by the denoiser are automatically added;

(*) V-Ray: Add "layers" type to override material exclude list;
(*) V-Ray: Add refraction filter bake element;
(*) V-Ray: Lower tessellation rate for out-of-view hair and displaced/subdivided geometry to save RAM in heavy scenes;

(*) V-Ray RT GPU: Add support for Orthographic camera;
(*) V-Ray RT GPU: Add support for bump with procedural Noise texmap;
(*) V-Ray RT GPU: Print the memory usage in the VFB statistics;
(*) VFB: Add option to enable auto-saving to history if the render completed normally (i.e. is not aborted);
(*) VFB: Add option to keep the VFB history folder relative to the current project path;
(*) VRayAerialPerspective: Add "filter color" parameter;
(*) VRayIES: Add an option to select luminous intensity in candelas (cd);
(*) VRayInstancer: Add option to override the node properties of the source objects;
(*) VRayStochasticFlakesMtl: Add textured flakes support;
(*) VRayStereoscopic: Add support for vertical placement of the left/right views in addition to side-by-side;
(*) VRayTriplanarTex: Add random modes: "By particle ID"/"By instance ID" support;
(*) VRayVolumeGrid: Implemented ability to pop out and enlarge the render diagrams;
(*) VRayVolumeGrid: Implemented different interpolation types per point in the render diagrams;
(*) VRayVolumeGrid: Implement motion blur clipping by the Cutter geometry for non-Mesh modes;
(*) .vrscene exporter: Show progress bar instead of "not responding" during export to .vrscene;
(*) V-Ray scene converter: Convert rectangle/sphere/disc photometric lights without web profile to the corresponding V-Ray lights;
(*) V-Ray Installer: Attempt to uninstall previous installation without registry record;
(*) V-Ray Installer: Installation options can be set from the command-line;
(*) ply2vrmesh.exe: Store the textures names used by OBJ files into user attributes;
(*) vrayspawner.exe: Make it possible to run V-Ray from a remote location;

Modified features:
(*) V-Ray: Faster rendering with the light cache;
(*) V-Ray: Blend the "Fixed" and "Adaptive" sampler UI into a "Bucket" image sampler;
(*) V-Ray: Enable support for processor groups and more than 64 CPU cores by default;
(*) V-Ray: Rename "Color threshold" to "Noise threshold" in the Adaptive image sampler;
(*) V-Ray: Add texmap shortcut buttons next to colors for plugins with automatically generated UI
(*) V-Ray: Add UI mode views switching for the Image Sampler rollout;
(*) V-Ray: Make the DR settings window with persistent size;
(*) V-Ray: Remove the "Adaptive subdivision" sampler from the UI
(*) V-Ray: Slow rendering of objects visible behind multiple panes of glass;
(*) V-Ray: The log messages window text and background match the 3ds Max color scheme;
(*) VRayLight: Streamline the UI rollouts;
(*) VRayLight: When assigning a new VRayHDRI or a Bitmap texture through the UI, automatically browse for a file and set the mapping to spherical environment;
(*) V-Ray RT: Add information about the current noise threshold to the render statistics;
(*) V-Ray RT: Enable region changes without restarting the render in RT;
(*) V-Ray RT: Enabled by default the rendering of Proxies, X-ref, Particle systems, Displacement and Motion Blur;
(*) V-Ray RT: Make override material independent for production and ActiveShade renderers;
(*) V-Ray RT: Optimize export of scenes with many instanced geometries with many faces;
(*) V-Ray RT GPU: Add "bias" spinners support for VRayDirt;
(*) V-Ray RT GPU: Improvement automatic texture resizing, leading to reduced memory usage and better quality;
