Official release

Improvements & bugfixes

• Adaptivity Clamp control is introduced in the Render Parameters' Optimizations section. The default value of 1.5 avoids excessive sampling of overexposed areas while a value of 100 disables this optimization
• ‘Viewport Texture Resolution’ option is implemented (Extensions > V-Ray > Preferences > Viewport Texture Resolution). It controls the size of all viewport texture previews of materials using the Bake binding mode
• Bake Binding Texture Mode is now enabled by default for newly created materials
• Fixed an issue with the V-Ray File Path Editor causing baked textures to lose their names and fail to render properly
• An issue preventing the V-Ray File Path Editor from archiving Raw Bitmap Buffer textures is resolved
• Scatter tool information is now displayed in the SketchUp Instructor tray and status bar
• Scatter Area Modifiers are now inactive when using '1D - On Splines' scattering mode to reflect that they have no effect on it
• Scatter's 'Normal Alignment' rotation option now accepts negative values. As a result Scatter instances can be aligned towards the vertical down (-Z) axis
• Scatter's UV Grid surface mode no longer ignores the size of the host’s group or component material
• Editing a Scatter guest's group or component no longer causes its instances to appear misaligned in the viewport
• An issue preventing interactive updates when deleting a Scatter widget is resolved
• An issue preventing interactive updates when adding an additional Scatter host is resolved
• Instances of Scatter objects duplicated during interactive rendering no longer disappear from the rendered image
• Fixed an issue preventing the update of Scatter asset's Guest list after deleting and reapplying a component as a guest twice in a row
• Fixed a crash caused by undoing and redoing the creation of a Scatter asset with enabled Scatter Viewport preview
• Added a 'Submit New' button to the Chaos Cloud window. Submitting consecutiveCloud rendering jobs is now possible without having to close and reopen the window each time
• An issue preventing the Cloud window from reloading automatically after updated Chaos Cloud application is resolved
• An issue causing updates of the Chaos Cloud application to produce errors is resolved
• Implemented safeguard logic which prevents the 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 correctly sets the current project's name in its File Path field
• Export V-Ray Proxy window now consistently provides the same output file name when being opened multiple times
• An issue preventing V-Ray windows from closing when opening a new file is resolved
• An issue causing the Animation Frame sliders to disappear in specific situations is resolved
• An issue causing the V-Ray UI to crash in rare situations is resolved
• Canceling the opening of a new SketchUp model no longer closes the Asset Editor
• The V-Ray Log window now correctly filters errors not caused by V-Ray and no longer pops up for such encounters
• The Adaptive lights optimization no longer causes artifacts in scenes containing Subsurface Scattering materials
• The Environment Background multiplier now affects the Sky texture's procedural clouds when rendered with V-Ray GPU
• The VFB no longer prints a localization error when rendering for the first time in a new session
• Removal of a V-Ray modifier from a Scatter's guest no longer deletes all instance previews from the viewport
• Opening scenes with missing Cosmos or Enmesh asset files no longer leads to errors
• An issue causing a crash after undoing and redoing a V-Ray Light creation during interactive rendering is resolved
• macOS: Fixed an error prompted by import of assets with auto-generated UI
• macOS: Entering sleep mode no longer severs the communication between V-Ray and SketchUp

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

Official release

Date - Dec 18, 2023

Improvements & bugfixes

• The behavior of the ‘Auto’ texture binding mode is restored to its V-Ray 6.10.03 state. In this mode, a bitmap texture connected directly or indirectly to the diffuse material slot is used as the primary viewport preview. Procedural textures and corrections are disregarded.
• A new ‘Bake’ texture binding mode is implemented. In this mode complex texture networks are baked to a single image used as a viewport preview. Differences between the rendered result and the viewport preview may occur due to the fact that only the texture confined within the 0 to 1 UV square is baked. This affects most procedural patterns and textures with custom UV placement configuration. Raytraced and Tri-planar textures are not supported
• A critical issue causing texture networks connected to the diffuse slot of specific materials to get deleted on scene activation is resolved. This was affecting projects saved with older V-Ray versions. Materials from such projects now open with the ‘Auto’ texture binding mode enabled. To enable the new procedural viewport texture preview navigate to the Binding rollout in the material properties and change the Texture Mode to ‘Bake’
• SketchUp materials promoted to V-Ray automatically use the ‘Auto’ texture binding mode which ensures that its raw bitmap buffer texture stored in SketchUp is rendered correctly. Changing the mode to ‘Bake’ will replace the buffer with the baked preview. It is recommended to save all raw bitmap buffers to disk before activating the Bake mode to preserve them
• An issue causing SketchUp to crash when closing down is resolved
• Fixed a number of issues with hiding a Scatter asset during interactive rendering
• 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
