vray CommandDescription
vrayBatchRenderActivates the Batch render tool.
vrayCamFocusActivates the camera focus distance tool.
vrayCamGuessVerticalV-Ray guesses the amount of lens shift that has occurred and compensates it accordingly. Note that this command is not usable in any default orthogonal view.
vrayChangeDefaultScene1Allows setting up the default V-Ray options based on the type of project - studio for product design or exterior for architectural visualization.
vrayDisplacementCreate=0 Creates a new displacement asset and applies it to the currently selected object.
Apply=1 Applies an existing displacement asset to the currently selected object.
Remove=2 Removes the displacement from the currently selected object.

vrayClipper

  

Create=0: Creates a Clipper.

Apply=1: A pop-up window prompts you to apply an existing Clipper.
Remove=2: Removes and existing Clipper.
vrayEdit

Allows you to select and edit any asset in the scene.

Materials - toggle, default = true. Allows selecting materials in NeUI based on the current selection in Rhino.
Objects - toggle, default = true. Allows selecting geometries in NeUI (fur, clipper, lights, etc..) based on the current selection in Rhino.

Select - list. Selection filter based on the current selection in Rhino and the Materials and Objects toggles.

 All - default. Selects all assets that will be acquired from the selection.
    Most - Selects the first most referred from the assets that will be acquired from the selection.
    First - Selects the first asset from the assets that will be acquired from the selection.
    Only - Selects the first and only asset from the assets that will be acquired from the selection. If multiple assets are acquired the command fails.

vrayEditMtl
UI Text Box
typewarning

This command is deprecated. Use the vrayEdit command instead.

Lets you select an object in the scene, whose material to edit.

vrayExportVRSceneExports the current scene into a .vrscene file.

vrayFur

Create=0: Creates and applies V-Ray Fur to the selected object.

Apply=1: Adds an already created V-Ray Fur from a pop-up window to a selected object.
Remove=2: Removes an existing V-Ray fur form a selected object.
vrayImportMaterial

Imports .vrmat assets.

vrayInfinitePlaneCreates a V-Ray Infinite Plane.

vrayLightDome

AtPoint=0: Creates a V-Ray Dome Light in a specified point and prompts you to choose an HDRI file.To directly input texture file path without invoking a file-picker window execute the command silently.
(e.g
_-vrayLightDome 0 0,0,0 "C:\Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\RhinoDefault.exr")

AsSphere=1: Creates V-Ray Dome Light as a sphere in a specified point and prompts you to choose an HDRI file. To directly input texture file path without invoking a file-picker window execute the command silently.
(e.g
_-vrayLightDome 0 0,0,0 "C:\Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\RhinoDefault.exr")
vrayLightIESCreates an IES light in the viewport and loads an .ies file of your choice.
vrayLightMesh

Create=0: Creates a Mesh Light.

Apply=1: Applies a Mesh Light to a selection.
Remove=2: Removes Mesh light properties from a selection.
vrayLightSphereLets you create a sphere light with a scale of your choice.
vrayLightSunFromDirectConverts a directional light into a Sun light.
vrayLockCamOrientationLocks camera position and orientation during Interactive Rendering.

vrayLoadSettings

File=0: Loads a .vropt file with render settings.
DefaultProduct=1: Loads a default .vropt file. You can choose between the default settings or a custom file.
vrayMtlFromRhinoConverts Rhino materials applied to selected objects into V-Ray materials.
vrayProxyExportExports a geometry as .vrmesh file and shows the Export Proxy window.
vrayProxyImportLets you import a .vrmesh or .abc file into the scene.

vrayRender

Production=0: Starts a Production render and displays the VFB.

Interactive=1: Starts an Interactive render. If it is rendering, stops the render.
Last=2: Starts rendering in accordance with the last type of render used.
Stop=3: Stops the current render process.

vrayRenderWindow2

Anchor

2

Similar to RenderWindow, RenderInWindow, and RenderBlowup commands, but ituses the Render Output settings as basis for region calculations instead. The region is specified in absolute image coordinates of its upper-left and lower-right corners. Manually drawing regions in the viewport is also supported.

Region=0: Renders a region of the image in the VFB. The specified region matches a manual-drawn region in the VFB, masking out the rest of the image. The masked out region appears black. This mode is suitable for image compositing.

CroppedRegion=1: Renders a region of the image in the VFB. The specified region matches a manual-drawn region in the VFB, cutting out the rest of the image.

 CropRegionBlowup=2: Renders a region of the image in the VFB. The specified region matches a manual-drawn region in the VFB, cutting out the rest of the image. The image height is altered so that the image aspect ratio matches the region aspect ratio, and the region width is scaled up to match the image width.

vrayScatter

Used for scattering either real or proxy geometry. It has create, apply, and remove options:

Create = 0: Asks the user to select objects of type: Converts objects to Scatter hosts. Object type can be surface, polysurface, mesh and extrusion, excluding InfinitePlane and Proxy special object type. If the selected objects are special objects, the tag is detached. A new Scatter object is created in NeUI and its tag is attached to the selected geometry.

Apply = 1: Applies an existing the Scatter special object modifier to the selected geometry. The user is prompted to enter objects. Enter or select the name of one of the Scatter objects available in the scene.

Remove = 2: Same as the Create command, but the operation stops at detaching Removes the Scatter modifier from the selected objects. Detaches the special object tag from the Scatter Host surface.

vraySelID

Selects object by given ID value.

vraySetMtlID

Random=0: Sets random colors as materials IDs to the select objects.
Black=1: Sets the selected objects' material ID color to black.

vraySetObjectID

Number=0: Sets an integer value as an object ID of the current selection.
Random=1: Sets random ID for each selected object.

vrayShowAssetEditor

Opens the Asset Editor.
vrayShowFilePathEditorOpens the File Path Editor.
vrayShowVFBOpens the V-Ray Frame Buffer.
vrayShowVFBonRender

No=0: Hides the VFB when rendering.

Yes=1: Shows the VFB when rendering.
vrayVPRSettingsChanges the viewport size.

vrayRecordAnimation

In Rhino 5, V-Ray Next automatically acquires animation data from Rhino. This command is useful only for choosing a Rhino animation over a previously set V-Ray Timeline animation in Grasshopper (via the Render in Project component). Creates a TexSky in the Environment map slot (automatically set to Rhino Document sun). Synchronizes V-Ray's environment with the current Rhino environment.

In Rhino 6, the command is replaced by the Animation Source option as the animation does not need to be pre-recorded.

vrayVantage

Opens V-Ray Vantage.
