Render

Begins the render with the last render control settings.

Render Control

Opens the render control dialog to allow adjustments of the render parameters before rendering.

Render with Take

Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.

Render

Begins the render with the last render control settings.

Render Control

Opens the render control dialog to allow adjustments of the render parameters before rendering.

Standard

Camera

The camera to render the scene from.

Visible Objects

Space-separated list of objects which will be rendered. Use * to render all objects (the default). You can use wildcards (for example prop_*) and bundle references to specify objects.

Visible atmosphere

Space-separated list of atmosphere objects which will be rendered. Use * to render all atmosphere objects (the default). You can use wildcards (for example fog_*) and bundle references to specify atmosphere objects.

Active Lights

Space-separated list of lights which will illuminate the scene. Use * to use all lights. You can use wildcards (for example key_*) and bundle references to specify lights.

Unload SOPs

Unload SOP geometry after used by the render.

Output Picture

The picture or device to be rendered.

Image Format

The file format (for example, Houdini pic) of the rendered image.

Valid frame range

Limits the rendering of frames, when set to Render frame range or Render frame range only.

Render any frame

Allow the renderer to render any and all frames.

Render frame range

Only render the frames in the range set below, but allow the renderer to render other frames if they are referenced by in-range frames.

Render frame range only (strict)

Only render the frames in the range set below, and don’t allow the renderer to render other frames, even if they are referenced by in-range frames.

Initialize Sim. SOPs

Force all simulation SOPs to be reset.

Generate Script File

Outputs an .ifd file instead of piping the script to mantra.

Binary Script File

Toggles between ascii and binary file formats.

Script File

Filename of the .ifd file.

Render Command

The command used to invoke the renderer. Can be modified with the popup window.

Render in Background

Continue to use Houdini while rendering.

Super Sample

Controls quality of anti-aliasing.

Decouple Ray Sample

Specify an alternate sampling rate for ray tracing. Ray sampling will use this value as a maximum sampling rate, and will take fewer samples if there is low variance.

Note

Decoupled ray sampling is only meaningful for micropolygon rendering. It will be ignored when mantra is run in ray tracing mode.

Resolution

Override camera resolution with values specified.

Pixel Aspect

Override camera pixel aspect ratio.

Fields

Control for rendering video fields.

Motion Blur

Specifies whether motion blur is allowed. If set to set to disallow, motion blur is globally turned off regardless of individual object settings.

Motion Blur Type

The default motion blur type for rendering. This can be overridden by an individual object.

Depth of Field

Turn on rendering of depth of field effects.

Jitter

Limits the amount of jitter. A value of 0 will result in no jitter.

Dither

Controls the amount of dithering performed.

Gamma

Gamma correction factor used.

Scripts

Pre-Render Script

Run this script before any rendering.

Pre-Frame Script

Run this script before each frame.

Post-Frame Script

Run this script after each frame.

Post-Render Script

Run this script after all rendering.

Extra parameters

Create Intermediate Directories

Create intermediate parent directories for output files as needed. This currently only applies to generated scripts, images, and shadow maps.

Skip Existing Frames

Skip rendering of existing frames. There are three values for this parameter.

Overwrite existing frames

This option will render every frame, regardless whether there’s a file on disk or not.

Skip frames that exist

If there’s a disk file that matches the vm_picture parameter, no render will be performed.

Skip frames that are valid images

If a disk file exists, the integrity of the image is checked before rendering is performed. This option incurs the cost of reading the image, but will re-render images that weren’t fully rendered.
