I'm creating custom variables inside the `Aliases and Variables…` window in Houdini, which get saved in my current hip file. I've primarily been using custom string variables throughout my workflow in file SOP's and ROP's. Is it possible to somehow override these variables with an hrender command-line option? I need to be able to render the same hip file multiple times with varying properties.

Any tips or examples would be appreciated. Or maybe there's a better approach entirely. Thanks,

If you open hrender in a text editor, you'll see that it's just a shell script that produces some boilerplate hscript and executes it with hbatch. You can easily make your own copy of it and add your own custom stuff. Personally, I just create a render.cmd file that i invoke with “hbatch foo.hip render.cmd” where render.cmd runs the (hscript) commands necessary to render and then quit.
