VRayFur styler (Alpha) ### VRayMesh - Added VRayPointParticleMtl material for shading point particles from .vrmesh/Alembic files ## **Modified Features** --- - Simplify the user interface - Added a "Min shading rate" prameter in the image sampler to control the number of rays shot for AA versus rays for other effects - Added a "Divide shading subdivs" parameter in the image sampler to prevent V-Ray from balancing shading subdivs vs AA subdivs for those users that find it confusing - Added light multiplier to the VRayMtlHair3 - Faster release of memory when using tiled OpenEXR or TIFF textures - Faster release of memory on Windows with subdivision surfaces after a render is complete - Faster export of Maya hair - "Speed" and "Velocity" outputs for the samplerInfo node - Sort the render elements list by alphabetical order - Store the number of samples in the SamplerRate render element for progressive sampler and RT - Material select render element is now able to take a set as an input - Intel Embree now supports proxies and instances - Intel Embree now requires only SSE2 instructions which means it supports older AMD processors - Enable fresnel for VRayMtl by default - Support for exporting list of specific nodes with the vrend command - Redirected all help links to the new official help web site - Print warning when trying to save an image to a location without write rights - Support for indexed tga files - Deep output from the VRayEnvironmentFog and Maya fluids - "Density" and "Frequency" attributes of the Maya noise texture are now mappable - Texture filtering extra attributes for the image planes ### V-Ray RT - Enable the rendering of particle systems - Improved refresh rate and pixel throughput ### **V-Ray RT/CUDA** - Native support for Maya Noise Tex - Native native support for Maya Solid Fractal ### VFB - When the "mono" button of the VFB is pressed, the computed intensity is now based on the selected R/G/B components only - Added support for the "track mouse" option while rendering for progressive sampling and V-Ray RT - Print the coordinates of the VFB region, while the user is drawing it - Write the frame stamp into OpenEXR files metadata - Color correction that allows a background image to be loaded - Delayed loading of VFB history preview images ### VRayMesh - Optimize scene loading times with many VRayMesh nodes - Optimized preview voxel loading - Added support for hair and particles color channels from Alembic - Option to flip normals for Alembic files - Option to render particles as points - Option to enable/disable Alembic full names support in the visibility lists - Support for render layer override for visibility lists ### VRayObjectProperties - Option to turn the reflection/refraction trace sets into inclusive sets - Ability to turn on/off the projection mapping with the "matte for secondary rays" option ### VRayVolumeGrid - Display the exact bounding box in the viewport - Show information about the available channels - Support for displacement - Support for additional lights - Added support for more render elements ### **ply2vrmesh** - Add a -velocityOffset parameter that allows to move the starting positions along the velocity vectors ## **Bug Fixes** --- - Metaballs do not work with object ID - Matte objects don't render as mattes in the lighting render elements - For 3D textures used as displacement textures on subdivided objects, the evaluation point is not on the subdivided mesh - Show VRmat Editor button is not working with Maya 2015 - Wrong reflections when disabling visible in reflections from the RenderStats tab - Wrong output with remapHSV and input constraints - Invalid colors with simple fog and ramp texture - Camera Dof is not being updated when render animation - Rendering with V-Ray corrupts the Maya UI for non-English versions of Maya - Camera Pre Scale and Post Scale are not working with V-Ray Physical camera - The material swatch background is black if V-Ray settings node is not created - V-Ray lights render wrong with Embree if ray packets are used - Setting Curvature threshold to 0 for NURBS object freezes the rendering - Maya Contrast shading node could produce invalid colors when input texture value is outside 0-1 - Light Select RE is deleted when using optimize scene size or delete unused nodes - Undoing V-Ray lights translation offsets the light target - V-Ray material ID attributes added to VRayHair3Mtl applied to Maya hair does not work - Fixed more cases of stuck buckets with GI - Crash when connecting V-Ray plugin texuture's "alpha from intensity" into Reflection glossiness of the VrayMtl - Crash with Maya fluids - Crash when rendering deformed particles - Occasional crashes when rendering swatches - Crash when creating nodes from some V-Ray plugins - Crash when initializing VRay for Maya 2014 on machines which do not support Viewport 2.0 - Crash when initializing if VRAY_FOR_MAYANNNN_MAIN_x64 is undefined - Crash with vector displacement and PlusminusAverage node - Dome light with non-uniform scaling renders incorrect - VRayMeshMtl shading group attributes are ignored ### VRayMesh - Fails to render properly if there are multiple objects in the file and VRayDisplacement is attached to the proxy - Fixed wrong rendering of multiple instances with particles/hairs - The offset in the Alembic file was ignored - Additional 2D/3D placement attributes for UV set name do not work for VRayMesh with displacement/subdivision - Use full names alembic option does not work for the shader list - Velocities should be taken into an account for alembic mesh bounding box computation ### VFB - Appears without its panel if it has been closed during the export phase - The Lens Effects were not applied to images loaded from the history - 2d pan and zoom doesn't work in RT if the VFB uses a region - "Hide render view" is not working if the vrayformaya plugin was loaded using userSetup.mel - Lens effects on images from the history is not working without at least on render - Freeze at render start with memory frame buffer and very large resolutions ### VRayObjectProperties - Maya crashes if omni/diretional light gets included in the exclude list of reflections/refractions sets - Visibility lists are not dimmed when thr object properties are disabled - The "disable" attribute do not work for the primary visibility and for fluids - Matterial attributes inside referenced nodes are ignored until changed ### VRayVolumeGrid / Maya Fluids - Different buckets in distributed rendering mode with light cache ### VRaySkinMtl - Raytraced subdivs parameter doesn't work, missing extra attributes ### Random MEL script error - Cannot find procedure "updateMayaSoftwareImageFormatControl" ### Progressive sampler - Does not create valid .vrimg files; - ExtraTex render elements render incorrectly with undersampling ### V-Ray RT - Applies color corrections to the Render View if VFB was once opened - Rendering Animation with RT is not affected by Render Elements settings - Disable the "use pixel aspect" option for the Viewport RT - Fixed the bounding box option for the selected objects in Viewport RT with Maya 2014 and above - Low cpu utilization if there are sections in the images that have been finished - Stretched image in Standalone RT - RT doesn't detect removing the physical camera attributes - RT doesn't start if render is cancelled before frame update finishes - V-Ray unloads textures when starting a RT render even when bitmap caching is enabled - The noise threshold doesn't work correctly ### V-Ray RT/CUDA - Crash if the card uses newer architecture that the supported by V-Ray - MayaLightDirect doesn't apply intensity to color - LightSelect RE renders wrong - Direct light render element is black if GI depth is 0 - Standalone crashes when missing CUDA/OpenCL device. It shoult fallback to RT/CPU in such case - Alpha gain and alpha offset are not working with procedural textures ### vrimg2exr - Fixed batch conversion output names generation ### img2tiledexr - Creates an alpha channel even if the input image does not have one - Writes wrong pixel aspect
