Parameters
Save to Disk
Saves the geometry to disk with the last control settings.
Save to Disk in Background
Starts another copy of Houdini in the background and instructs that copy to cook and save the geometry. This allows one to continue working and load the .bgeo files as they complete.
Controls…
Opens the control dialog to allow adjustments of the render parameters before rendering.
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.
Start/End/Inc
Specifies the range of frames to render (start frame, end frame, and increment). All values may be floating point values. The range is inclusive.
These parameters determine the values of the local variables for the output driver.
Render with Take
Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.
Save to Disk
SOP Path
The SOP node, object, or SOP subnet to render from.
Output File
The file to save the geometry to (should end in .geo or
.bgeo). Make sure to include $F in the
filename to write out separate
files for each frame.
Transform
Specifies whether the geometry should be transformed into world space before written out.
Initialize Simulation OPs
Forces all simulation OPs to be reset. This includes DOP Networks, POP SOPs, and other OPs that cache their results.
This is the safest way to render out a simulation, because it starts the simulation from scratch and discards any partial simulations you might have done with different parameters.
Alfred Style Progress
A percentage complete value is printed out as files are written. This is in the style expected by Pixar’s Alfred render queue.
Report Network Use
The number of bytes sent or received by the distributed simulation primitives during the cooks triggered by this geometry output is printed.
This does not track use by, for example, saving a file to an NFS mount. It only tracks the network communication of nodes such as the Gas Net Exchange Border DOP.
Save Retries
If saving the geometry to disk fails due to a disk writing error, Houdini will usually error the output node immediately. This is desirable for most cases where a failure to save means an illegal path, which is not recoverable. However, sometimes files fail to save due to network issues. If the number of save retries is non-zero, Houdini will re-attempt to save this number of times. Each time will be accompanied with an output to the console of the failure to save and a five second wait in the hopes that the network will clear up.
Save in Background
When saving more than one frame, save in a background thread. This can make saving faster for large file sizes, but may use more memory since it will retain the output geometry until the save completes.
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.
Locals
N
Frame being rendered.
NRENDER
Total number of frames being rendered.
