This page discusses the render settings in V-Ray for Houdini.



The V-Ray Renderer (vray) node contains a multitude of options for V-Ray. These settings include rendering speed and quality, global overrides, indirect illumination, caustics, and distributed rendering.

Additional rendering settings related to environment overrides can be accessed from the V-Ray Environment (env) node.

V-Ray Renderer Node


Render to Disk – Starts a V-Ray render.

Controls... – Launches the Houdini Render Control window.

Valid Frame Range – Specifies the frame(s) to render.

Render Current Frame – Renders the current frame.
Render Frame Range – Renders frames from the specified range set below as well as other frames if they are referenced by in-range frames.
Render Frame Range Only (Strict) – Only renders the frames in the specified range set below.

Start/End/Inc – Specifies the range of frames to render (start frame, end frame, and increment).

Render With Take – Renders using the settings from a specified take.

Camera – Specifies the camera to render from. The camera specified by this path must be a valid camera object in the scene, otherwise nothing will be rendered and an error will be logged in the console.

Override Camera Resolution – When enabled, the camera's resolution will be overridden, and the resolution specified from the V-Ray Renderer will be used instead.

Bake to Texture – When enabled, exposes the Bake tab which contains the Texture Baking controls for the Renderer. V-Ray will produce an image in UV space instead of rendering through the specified camera.

Environment – Specifies the Environment ROP to use with the current Renderer. Multiple V-Ray Renderer nodes can link to the same Environment.

V-Ray Renderer Tabs

  • Export – The Export tab provides cloud and IPR rendering options, as well as setting .vrscene export and selecting the rendering engine (GPU, CPU).
  • Images – Controls the output render image settings.
  • Renderer – The Renderer tab holds a number of important settings defining the final V-Ray output.
  • Effects – V-Ray Volumetric effects can be controlled from this tab.
  • Objects – This tab is standard for Houdini. For more information, visit Houdini's documentation.
  • Script Here are listed some V-Ray related script examples. This tab is standard for Houdini. For more information, visit Houdini's documentation.

Environment Node

The Environment node render settings are accessed by creating a V-Ray Environment node. See the V-Ray Environment page for additional information.
