We do not recommend running Apprentice or Indie licenses on the same machine as Commercial licenses.

If different license types are mixed on the same machine, there are ways to mitigate the risk or tainting commercial files.

Add the following environment variable to houdini.env:

To ensure only an Indie license is checked:

HOUDINI_LIC_OPT="---check-license-modes=indie -skip-license-modes=commercial,education,apprentice"

To ensure only a Commercial is checked:

HOUDINI_LIC_OPT="---check-license-modes=commercial -skip-license-modes=indie,education,apprentice"

There are more variables that may be used to control different components of Houdini such as hython. For example:

HOUDINI_HYTHON_LIC_OPT

You can also issue these options on the command line when launching Houdini:

houdini --check-license-modes="commercial" --skip-license-modes="indie,education,apprentice"
