**Date** – July 7, 2014

 

## **New Features**

---

### Render Settings

- "Render mask" option to (re)render only a subset of the scene nodes

 

## **Modified Features**

---

- 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
- Help messages for the vrend MEL command
- 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

### VRayMtl

- the default cuttoff threshold is now 0.001 instead of 0.01 for new materials

### VRayFastSSS2/ VRaySkinMtl

- Optimized raytraced multiple scattering

### V-RayMesh

- Support for alembic hair uvs

### 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

### Sampler Info

- New extra V-Ray attribute to specify which UV set should be returned from the uv output

### ply2vrmesh

- Swaps vertex-color-channel-names during the conversion
- Doesn't transfer vertex colors with houdini mesh
- 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
- Shutter efficiency uses wrong formula
- The progressive sampler doesn't update properly the Maya's progress bar
- 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

### V-Ray RT

- Renderable curves param changes are not detected
- Changing the shader of VTayMtlOSL while RT is running crashes Maya
- Changing the Color Space parameters of OCIO texture is not detected
- Using -rtsamplelevel with the command line leads to very slow calculations
- Crash with 2d pan and zoom

### VFB

- Maya crashes when an image is being deleted/removed from the render history

### VRayMesh

- Alembic particles and hair imported as proxies don't render with VRayMtl
- .vrmesh files with hairs do not quite respect the dynamic memory limit
- Crash during the export, if the mesh has color set selected for velocity
- Clipped particles when motion blur is on

### VRaySwitchTransform

- Fatal error building the scene if connected shape-node is deleted/removed

### VRMatMtl

- The ASGVIS V-Ray plugins are missing from the OSX installation causing inability to render ASGVIS vismats

### Maya fluids

- Locity render element and Maya hair, when motion blur is off
- Rendering issues with adaptive grid and motion blur
- The Shadow Opacity was not working like with Mental Ray

### XGen

- When doing a maya batch render (from the UI) no instanced XGen geometry is rendered
