I'm having trouble with a package when saving data in the background with a SOP File Cache, so I want to disable the package for Houdini instances started from this node. I tried using an Environment Edit inside the File Cache's `topnet1` to disable the package (its loading is controlled by an environment variable), but this doesn't appear to work. I'm not sure if the environment is being changed at the right time, or at all.

Any suggestions? I've attached a sample setup. Thank you.
