Improvements & Bug Fixes

• Integration
  • Experimental support for Rhino 8 is added
  • All the default VFB shortcuts are now correctly set
  • An issue causing materials assigned to blocks which are not instantiated in the project to be incorrectly purged, is resolved
  • The Decal viewport widget is updated to more clearly show the projection’s orientation
  • The Decal’s creation logic is updated to allow precise initial positioning and orientation. The first selected point determines the lower left corner of the Decal projection, the second determines the upper right corner and the third, sets the widget height
  • The Decal's material is no longer duplicated after its deletion is undone
  • Setting the Decal’s material to ‘None’ now correctly triggers interactive rendering update
  • Plane input is now used for positioning and orienting Rectangular Lights in Grasshopper. Legacy definitions can be migrated and will continue working as before
  • The Scatter’s density map is now correctly placed based on the object UVs
  • Camera FOV animations created in Grasshopper are now correctly exported to vrscene files
  • An issue causing a crash when V-Ray plugin is manually loaded in specific situations, is resolved
  • An issue leading to incorrect results when one of the Dome light options - Affect Specular or Affect Reflections is disabled, is resolved
• Script Access
  • V-Ray Python script transaction wrapper implemented. Use the following statement ‘with vray.Scene.Transaction():’ followed by the changes that should be wrapped in a transaction, instead of the previously available ‘BeginChange()’ and ‘EndChange()’ functions
  • Four of V-Ray's Python scripting API functions are renamed. ‘PluginsByClass()’ that queries plugins by type name is changed to ‘PluginsByType()’; ‘PluginsByType()’ that queries plugins by category name is changed to ‘PluginsByCategory()’; ‘Plugin.Class()’ changed to ‘Plugin.Type()’; ‘Plugin.Type()’ changed to ‘Plugin.Category()’
  • Running one of ‘SaveSettings()’ or ‘LoadSettings()’ V-Ray Python API function now correctly returns a boolean result
  • An issue with the ‘PluginsByCategory()’ and ‘PluginsByType()’ V-Ray Python API functions is resolved. Setting their second argument to True now correctly returns only top-level V-Ray plugins
• UI
  • Progressive Caustics implemented. The new mode can be enabled in the Calculation Mode/Disk Caching rollout. In Progressive mode the caustic effect is produced during rendering (progressive image sampler has to be used). There is no additional prepass required and no photon map is stored
  • A number of new parameters are exposed for the Curvature texture - Mode, Radius, Ignore Bump, Output Gain, Output Lift, Output Gamma, Output Pivot, Output Clamp
  • Backside Projection Decal option implemented. Enable it to see the Decal effect on a backside of a surface
  • Deleting a large number of materials at once is optimized. Deleting all the V-Ray Library materials (more than 300), for example, now takes less than a minute
  • Some of the default internal GPU engine (CUDA/RTX) parameters are updated to decrease memory usage and improve performance. Scenes saved with previous V-Ray versions are automatically migrated
  • All NeUI errors are now correctly logged in the Log Window
  • In issue causing a SettingsRTEngine.gpu_light_cache warning message to appear in the render log is resolved
  • An issue preventing the link in the new version update popup notification to work, is resolved
  • An issue causing the initial state of the SettingsOptions.ray_bias V-Ray parameter to be incorrectly set by default is resolved. The internal value that V-Ray uses now always corresponds to the UI state
  • An issue causing errors to pop up when the Material Library or Light Gen content download is interrupted is resolved. The message type is changed to a warning
  • The current project name is now automatically suggested in the Export V-Ray Scene window
  • The Scatter’s Seed parameter tooltip is updated
  • An issue causing long Scatter guest names to overlap in the guests list is resolved
