Figure 1: Octane ROP Scripts parameters
Each script command refers to an hscript command which will be run, regardless of the expression language selected for the parameter. The resulting string runs as an hscript command. It is possible to use the python, unix, or source hscript commands to perform complex processing.
The commands always run when rendering occurs. The command checks the output driver's parameters while rendering a range or sending output to a command.
Before the render occurs, Houdini® sets the current hscript directory to point to the output driver.
Pre-Render Script - This command runs before OctaneRender® generates any IFDs. It runs once per render.
Pre-Frame Script - This command runs before generating each IFD.
Post-Frame Script - This command runs after generating each IFD. After the IFD generates, OctaneRender doesn't always finish rendering the image.
Post-Render Script - This command runs once after generating all IFDs. After the IFD generates, OctaneRender doesn't always finish rendering the image.
