This output operator is the wireframe renderer. The operator sets up all necessary options and then invokes the renderer. Alternatively, the output can be saved to disk as a script file to be rendered later.
When rendering postscript, the width and height of the image represent the width and height of the “paper” (in inches). Thus to render landscape mode, the width should be set to 11 and the height set to 8.5. The postscript options can be set by clicking the + button beside the render command.
Arguments may be passed to the script and variable expansion is done before calling the script.
Note
The Wren ROP uses the linewidth
attribute, if present, to determine the width of the line.
Tip
To render files readable by Adobe, you need to use the paper width and height options.
Parameters ¶
Save to Disk
Begins the render with the last render control settings.
Controls
Opens the Render Control window, which allows you to adjust 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.
Valid Frame Range
If on, the render is only valid between the start and end frames, at the specified frame increment. If a frame is outside the range, or falls on a frame that isn’t included by the frame increment, the frame will not be rendered.
If off, the render is valid at any frame.
Note
If you want to temporarily set a sub-range to render, use the 'Frame Range' parameter in the Render Control dialog (click the Render Control… button at the top of this dialog).
Output Picture
Where the output of the render should be directed.
Camera
Which camera to render the scene from.
Visible Objects
List of objects visible in the rendered scene.
Unload SOPs
Unload SOP geometry after used by the render.
Use Display SOP
Use the display (instead of render) SOP.
Create Intermediate Directories
When turned on, creates intermediate parent directories for output files as needed. Currently only applies to generated scripts, images, and shadow maps.
Initialize Simulation OPs
Forces all simulation OPs to be reset. This includes DOP Networks, POP SOPs, and other OPs that cache their results.
Generate Script File
Outputs the renderer’s script file instead of feeding the data to the renderer directly.
Binary Script File
Toggles between ascii and binary file formats.
Script File
Filename of the script file to create.
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
Number of rays sent per pixel in x and y when antialiasing.
Override Camera Res
Allows specification of the render resolution.
Resolution
Resolution to render at.
Pixel Aspect
Specifies pixel aspect ratio of the intended viewing device.
Jitter
Limits the amount of jitter. A value of 0 will not produce any jitter.
Pre-Render Script
Execute this script before any rendering.
Pre-Frame Script
Execute this script before each frame
Post-Frame Script
Execute this script after each frame
Post-Render Script
Execute this script after all rendering
Locals ¶
N
The current frame of the range specified. This always starts at 1.
NRENDER
Total number of frames being rendered.
