Improvements & bugfixes

• Adaptivity Clamp control is introduced in the Render Parameters' Optimizations section. It can be used to avoid excessive sampling of overexposed areas.
• Scatter Area Modifiers are now inactive when using '1D - On Splines' scattering mode to reflect that they have no effect on it.
• Fixed an issue preventing Scatter's 'Normal Alignment' rotation option from accepting negative values. Scatter instances can now be aligned towards the vertical down (-Z) axis
• Scatter guests with V-Ray Fur are no longer omitted from being rendered
• Improved Scatter UV Grid surface mode handling of host objects with different mapping channels
• Fixed an issue where Scatter's points previews are not drawn on the host's surfaces when Bounding box volume center guest origin is selected
• Fixed an issue causing removal of V-Ray special objects from a Scatter's guest to delete all instance previews from the viewport
• Added a 'Submit New' button to the Chaos Cloud window. Submitting multiple Cloud rendering jobs is now possible without having to close and reopen the window each time.
• Fixed an issue preventing the Cloud window from reloading automatically after updated Chaos Cloud application
• An issue causing updates of the Chaos Cloud application to produce errors is resolved
• Implemented safeguard logic preventing V-Ray log files from reaching abnormal size
• An issue causing an incorrect state of the Export button in the Export V-Ray Proxy window is resolved
• Export V-Ray Scene window now always uses the current project's name in its File Path field
• A valid default file path is now used in the Export V-Ray Proxy window
• Export V-Ray Proxy window now consistently provides the same output file name when being opened multiple times
• Fixed an issue preventing V-Ray windows from closing when opening a new project file
• Fixed an issue causing the Animation Frame sliders to disappear in specific situations
• An issue causing the V-Ray UI to crash in rare situations is resolved
• Added support for edge softening adjustments during Interactive rendering in Rhino 8
• Added support for Rhino 8 Blend materials
• Added access to the Sun creation window via the V-Ray toolbar's Sun icon in Rhino 8
• Added support for Rhino's native Clipping Plane inclusion and exclusion list in Rhino 8. A migration for preexisting scenes is implemented to ensure synchronization between the V-Ray and Rhino lists
• V-Ray properties tab no longer appears empty in Rhino 8.3
• Unassigned materials from vrscene files are no longer imported via the V-Ray Scene Importer
• An issue leading to material loss when importing a linked block with other nested blocks is resolved
• IES lights contained within Cosmos assets now produce the same illumination after asset merge
• An issue producing artifacts in subsurface scattering materials when adaptive lights are used is resolved
• The Environment Background multiplier now affects Sky texture's procedural clouds when rendered with V-Ray GPU
• Rhino render resolution is now synchronized with V-Ray upon V-Ray activation
• Grasshopper: Added viewport preview options for V-Ray Proxy Meshes, Proxy Scenes, and Cosmos Assets. The preview modes are: a simplified mesh, whole mesh, a bounding box or a point
• Grasshopper: Instancer component plugged in an Infinite plane component is now considered for calculating the automatic Z Offset
• Grasshopper: An issue causing data loss after upgrading Light Rig components from older versions is resolved
• Grasshopper: Fixed an issue with incorrect Surface Scattering Slope Limitation and Slope Angles values in specific situations after upgrading Scatter components created with previous versions
• Grasshopper: Fixed a crash when adding a Proxy Scene as a Scatter Guest

V-Ray 6, Update 2, hotfix 1 (6.20.01)

Official release

Date - Dec 18, 2023

Improvements & bugfixes

• An issue causing textures to appear tiled incorrectly in the Rhino viewport in specific situations is resolved
• Using a UVW Placement asset in a texture to no longer provokes its viewport preview to be baked
• Bitmap resolution matching implemented. This feature ensures that the baked viewport preview of texture networks containing a bitmap matches the bitmap resolution. It is enabled by default
• The viewport preview texture baking settings can now be changed. Use the ‘vrayTexturePreviewSettings’ command to change the resolution or to toggle the new bitmap resolution matching feature
• Bump amount is now correctly taken into account when previewing materials in the viewport
• Rhino 8: V-Ray now successfully renders lines using the Curve Piping modifier
• Dome Light textures are now successfully imported with the V-Ray Scene Importer. The texture orientation is automatically adjusted for scenes with Up Axis different from Rhino's
• An issue leading to a crash upon opening the Asset Editor with specific V-Ray 2 scenes is resolved
• Using any link in the About window no longer produces errors
• Fixed a number of typos and a missing label in the Asset Editor
• Scatter’s random rotation transform step now correctly uses degrees instead of radians
• An error in the File Path Editor prompted by missing files is resolved
