Most numeric V-Ray parameters come with a slider to make fine-tuning for easier adjustment. Each slider is set to a default range of recommended or commonly used values. If a value above or below that range is used the slider adapts by increasing or decreasing its range accordingly (2x the input value) to maintain usability. If a value below the current slider range is used, the slider again adjusts its range by shrinking it to twice the amount of the input value.

Тhe slider range does not indicate the parameter's total minimum and maximum input values. The  The absolute minimum and maximum values of each parameter can be found by hovering over its spinbox.

Asset Tagging

Custom grouping scene assets of any type is now possible in the V-Ray Assets Outliner. A new Tag View button allows toggling tags visibility on or off. It is located at the top-right corner of the Asset Outliner, next to the search field. Tags help to organize and work more efficiently in complex projects. Upon creation each tag is assigned a random color. 

Each tag can be assigned to multiple assets all at once via the context menu and one asset can be assigned multiple tags. Tags can be assigned to assets of all categories - materials, textures, lights, etc. When a tag is assigned to assets of different types, the tag indicator appears in each category.

Right-clicking on a tag allows its renaming or deletion. Alternatively, double-clicking a tag name allows its renaming directly.

Right-clicking on any asset and hovering over its "Tag" context menu entry displays a list of all available tags in the scene, as well indicators which tags are currently assigned to the asset.

Dragging an asset over a tag assigns the tag to this asset.


UI Text Box

  • Tags are considered scene-specific, meaning they are serialized in each project file and they cannot be transferred between scenes.
  • Saving any asset as a .vrmat does not write its tags to the file keeping it clean of any scene-specific data.
