Removed Linear Workflow - Enlarged Material Library - Provided export/import of Global Material Overrides settings - Improved Dome Light behavior in case of missing HDR map ### Interactive (RT) Rendering **RT is updated during the following changes:** - Scale and rotation of V-Ray Materials - V-Ray Material updates in Standalone Material Editor - Swapping of diffuse textures - Scale and rotation of Diffuse Textures - Swapping of color materials ### Channels - Added **Material ID** render element - Added **Material ID (No AA)** render element ### User Interface - Added Obtain License on Start-up option to General Settings - Added text-input field in Material Paths browsing dialog - Added file format selector of auto-saved images - Added export/import option for V-Ray Swarm settings - V-Ray Swarm settings section is completely updated - Added Exclude local machine option to Swarm settings - Swarm master node can be configured by IP and port - Swarm resource usage goal is defaulted to 60% - Improved Sun Intensity precision - Use GPU Denoiser setting is enabled by default - Affect Background parameter of Environment Fog is enabled by default ### Infinite Ground Plane - Improved Infinite Ground Plane material behavior - Improved Infinite Ground Plane integration with Global Material Overrides in RT - Improved Infinite Ground Plane support for RT GPU rendering - Infinite Ground Plane material settings are now saved per project ## **Bug Fixes** --- ### General - Issue with Revit freezing when no V-Ray licenses were available - Issue with continuous rendering when new Revit project was opened - Issue with unreleased DR nodes when Swarm was disabled - Issue with Dome Light color not being exported/imported properly - Crash when auto-save and denoiser were enabled simultaneously - Issue with units scale conversion of V-Ray materials bump amount - Issue with objects not being overridden on Global Material overrides - Issue with V-Ray not using sRGB color space - Error with rendering a workshared project after workset ownership had been delegated - Error on Revit exit when 2 instances of Revit were open - Issue with units conversion of Aerial Perspective settings ### Export from Revit - Issue with downscaled ortho 3D views - Issue with IES files export from Revit - Crash with IESFileLocation not being configured in the Revit.ini file - Issue with textures placed in folders containing underscore/s in their names - Issue with Revit lights dimming set to 0 not being respected by V-Ray - Crash with disappearing Revit objects when paths to assets were too long - Issue with RPCs nested in a family not being rendered - Issue with geometries not being properly cut when using Section box - Issue with artifacts when mapping spherical objects - Issue with AutoGen materials blending color and texture being rendered either white, or excluding the texture - Issue with instanced families being all cut when linked to Revit and partially intersected by Section box - Issue with incorrect mapping of imported .DWG geometries - Issue with AutoGen materials placed underneath a decal not being exported at all - Issue with units conversion of Revit metal materials pattern height - Issue with displacement continuity not being respected by V-Ray - Issue with Infinite Ground Plane not being rendered when using a displacement map - Issue with APT_Distance properties not respecting Revit units like RPC Height, Texture Real World Scale, Offset and Angle etc. ### Interactive (RT) Rendering - Crash in RT CPU after V-Ray Material displacement updates - Issue with disabled RT updates on RT restart - Issue with unmapped objects inheriting material updates of mapped ones - Issue with material scale and rotation not being overridden by Global Material overrides - Error with NullReferenceException in RT ### V-Ray Virtual Frame Buffer (VFB) - Issue with channels not being saved individually out of VFB - Issue with Render last button not updating the rendering - Crash when clicking Render last after an object was deleted in Revit - Issue with Lens Effects Settings being slided off the window after Resolution changes - Issue with ∗.vrimg file being overexposed when loaded to VFB with bloom effect on - Crash when clicking Render last button on freshly opened VFB - Issue with VFB options being reset to default when switching RT engines ### User Interface - Issue with Sun and Dome light settings panels not being mutually exclusive - Issue with Image Sampler being incorrectly exported into ∗.vrscene file - Error while browsing for V-Ray Material files - Issue with channels selection being saved globally - Issue with toolbar buttons not updating accordingly when switching between Revit projects - Issue with Current View not being updated when renamed in Revit - The following units were not updated on Revit project units change: Focus Distance; Fog settings; Object settings - Issue with texture file association being broken after its path was removed from Material Paths - Issue with Current View being reset to default when switching between Revit projects - Issue with Rendering Progress remaining open on license release - Crash when File Browse dialog was opened with invalid initial file path - Issue with all render elements being saved to Project Gallery - Help links in Settings dialog were not updated - Issue with Camera Mode drop-down being disabled after RT rendering had finished - Procedural Geometry Tesselation controls were not restricted from 0 to 15 - Import Options columns had no MinWidth - Issue with special characters in Swarm tags not being displayed in the UI - Issue with Inscatter Multiplier of Aerial Perspective being not respected - Denoiser and ZDepth settings were not disabled if the corresponding channel was disabled ## **Known Issues** ---   - Issue with identical families disappearing from rendering - Changing the Atmospheric Height and View Distance of Aerial Perspective is not properly applied during RT CPU - In case you receive the below error when starting Revit after installation of V-Ray for Revit plugin, follow the steps to resolve it
