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.

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.
