V-Ray for Maya 3.0 beta 3 (7 July 2014)
==============================================
New features:
(*) Render Settings: "Render mask" option to (re)render only a subset of the scene nodes;
Modified features:
(*) VrayMtl: the default cuttoff threshold is now 0.001 instead of 0.01 for new materials;
(*) VRayFastSSS2/VRaySkinMtl: Optimized raytraced multiple scattering;
(*) Optimized rendering performance with tiled textures;
(*) Optimized primary visibility with maya hair and vray proxies;
(*) Reduced the memory usage for hair and particles;
(*) An IOR parameter for the VRayEnvironmentFog shader;
(*) VRayMesh: support for alembic hair uvs;
(*) Help messages for the vrend MEL command;
(*) VRayLightMtl: option to multiply the intensity by the opacity;
(*) Render Settings: The "Clear render view" option should be renamed to "Clear frame buffers" and work also with the VFB;
(*) samplerInfo: new extra V-Ray attribute to specify which UV set should be returned from the uv output;
(*) Remove the pre-render export (and the MAYA_DISABLE_BATCH_RUNUP env variable) when using the "Use camera path" GI option;
(*) Disable clamping of velocity render element by default;
(*) Option to manually clear the geometry and bitmap cache;
(*) Ability to use OS native browser when Importing V-Ray proxy;
(*) Automatically connect a placeEnvTex to a file node for a material environment override;
(*) ply2vrmesh swaps vertex-color-channel-names during the conversion;
(*) ply2vrmesh doesn't transfer vertex colors with houdini mesh;
(*) ply2vrmesh: print the number of (preview) hair/particles with the "-info" option;
(*) vrimg2exr: print information about the rendered region in the image with the "-info" option;
Bug fixes:
(*) NURBS surfaces do not generate velocity information;
(*) XGen: when doing a maya batch render (from the UI) no instanced XGen geometry is rendered;
(*) Shutter efficiency uses wrong formula;
(*) VRayMesh: Alembic particles and hair imported as proxies don't render with VRayMtl;
(*) VRayMesh: .vrmesh files with hairs do not quite respect the dynamic memory limit;
(*) VRayMesh: Crash during the export, if the mesh has color set selected for velocity;
(*) VRayMesh: Clipped particles when motion blur is on;
(*) VFB: Maya crashes when an image is being deleted/removed from the render history;
(*) VraySwitchTransform: fatal error building the scene if connected shape-node is deleted/removed;
(*) The progressive sampler doesn't update properly the Maya's progress bar;
(*) VRMatMtl: The ASGVIS V-Ray plugins are missing from the OSX installation causing inability to render ASGVIS vismats;
(*) Light mesh crashes with animated alembic meshes when the topology changes;
(*) The Maya render view updates slower than the VFB;
(*) Disabling cached geometry leads to crashes on Linux;
(*) Invisible lights show up with global volumetrics;
(*) Different naming convention for multichannel EXR;
(*) Folders are created when vray is set not to save images;
(*) TexRemap animated color position outputs wrong value;
(*) Incorect velocity render element when converting to a Polygon Dynamic Mesh;
(*) Crash with velocity render element and Maya hair, when motion blur is off;
(*) Maya fluids: rendering issues with adaptive grid and motion blur;
(*) Maya fluids: the Shadow Opacity was not working like with Mental Ray;
(*) V-Ray RT: Renderable curves param changes are not detected;
(*) V-Ray RT: Changing the shader of VTayMtlOSL while RT is running crashes Maya;
(*) V-Ray RT: Changing the Color Space parameters of OCIO texture is not detected;
(*) V-Ray RT: Using -rtsamplelevel with the command line leads to very slow calculations;
(*) V-Ray RT: Crash with 2d pan and zoom;
