- Ability to select the render camera by right-clicking in the VFB window ### GLSL - New built-in functions: sinh, cosh, tanh, frexp, lit, fresnel ### VRayVolumeGrid - New render controls that allow proper rendering of FumeFX imported files ### VRayMtl - Added GGX reflection brdf ### VRayCarPaintMtl and VRayFlakesMtl - Added reflection depth limit ### XGen - Added ability to animate the color of XGen archives through expressions ### V-Ray RT GPU - Take into account the AA filter settings as much as possible ### ply2vrmesh - added an option to merge two or more .vrmesh files into one ### vrimg2exr - The -info option now prints a message if the file is partially written - Added -multiPart option to that produces an OpenEXR 2 file with each render element in its own "part"   ## **Bug Fixes** --- - Transferring assets does not transfer vrsssmap files - EXR textures are always loaded as 32-bit floating point - Low precision of 32-bit tiled EXR - Slow rendering of subdivision surfaces in certain cases - Difference in interpretation of alpha when using files without alpha channel - Connecting an image into RectLight's alpha is not working - Moving a layered texture slot connected to VRayPluginNodeTex crashed Maya - Maya crashed if a scene was loaded while V-Ray was still rendering - Fixed slower rendering when using Maya's Render View compared to using the VFB - Progressive sampling + DR + "Don't render final image" did not finish rendering - V-Ray materials did not respect the display/render layers for the lights in Viewport 2.0 - When "Use irradiance map option" of a diffuse material was turned off, Maya crashes - V-Ray crashed when the "Flake map size" option for the FlakesMtl or CarPaintMtl was too large - Fixed various issues with VRayMtl on back-facing surfaces - VRayCarPaintMtl and VRayFlakesMtl with flake glossiness 1.0 resulted in invalid colors - VRayUserColor didn't work with VRayLightMesh and VRayLightMtl material with "direct illumination" enabled - Exporter's memory was not deallocated with hair and "Use camera path" - "Use camera path" produced wrong result when used with "Camera and Aim" after beta 3 - The dome camera didn't work with FOV bigger then 165 degrees - Fixed crash with spherical harmonics GI - Fixed wrong rendering with multiple VRaySoftbox textures on the same scene - Fixed crash with renderable curves - Fixed incorrect filter file names for V-Ray nodes in the various dialog boxes - Don't hide the RenderView when pressing the Stop button in the VFB and "Hide Render View" option is disabled - The Pause IPR button of the Render View was not working - The default VFB stamp font was too small on OSX - When proxy Alembic offset was on, animated proxies wouldn't render correctly - Fixed crashes with Embree in specific scene - The VRaySun went wild if moved along the object axis - Save and load dialogs didn't remember their last used paths - Undo didn't work for changing the material connection to VRayMeshMtl ### V-Ray RT - Fixed slowdown with render elements when working in the viewport - Fixed random crashes when rendering motion blurred meshes with changing number of vertices - The RT server didn't start automatically on Fedora 20 - The RT ignored VRayProxy animation when the timeline was scrubbed - Hiding VRayMetaballs node stopped the RT - Fixed crash if RT is frequently restarted ### V-Ray RT CUDA - Fixed wrong VRayDirt in VRayExtraTex RE - Fixed crash with dome lights - Some render elements caused data shift in the wrong channel - The "Invert normals" option of VRayDirt had no effect on backside polygons - Maya Noise texture was broken with beta 3 - Error API 700 with specific scene ### VFB - Random crashes on Linux with the VFB history - Odd files in the history were saved when the save button was pressed a few times fast - .vrimg files without saved preview in history folder did not reflect srgb on/off state - Fixed the stand-alone VFB support on 64-bit Mac OS X - Fixed render region shift when another scene is opened - The VFB window was missing after you dock the panel and then reset the layout ### VRayVolumeGrid - Disabling the diffuse color renders black smoke - The bounding box is not visible in Viewport 2.0 - Slow rendering with glossy reflections - Failure to load the cache file when using relative paths ### XGen - Some VRayObjectProperties were not working with xgen archives ### Distributed Rendering - 2.4 to 3.x DR-settings translation caused wrong ports for rendering ### VRayToon - Fixed random crashes when rendering with "World Units" - Rendering with "World Units" produced random artifacts - Line width of 0.0 produced random artifacts ### ply2vrmesh - Fixed conversion hang with high poly count object - obj converted to vrmesh produced corrupt mesh in Maya when "Show whole mesh" or "Create a mesh from this proxy" were used ### img2tiledexr - img2tiledexr and vrimg2exr don't start in GUI mode on OSX
