License Acquisition FAQs


License Acquisition

These license acquisition tables list what licenses are checked by Houdini applications through the client helper program hserver.

Note: As of Houdini 13.0, the Houdini Batch license type has been superseded by the Houdini Engine license type. As of Houdini 8.2, the Non-Graphical, Render Script and Select license types no longer exist.

Houdini Non-Graphical and Render Script are now included in the Houdini Engine license. They are listed here for those customers who are still running legacy software.

The tables below are based on how the client starts hserver. The column to the left refers to the license type that will be requested from the license server. The column on the right refers to the product that the client is asking for (based on the commands):

Product Name License Type Executable Name(s)
Houdini FX Houdini-Master houdini, houdinifx, hmaster
Houdini Houdini-Escape hescape
Houdini Engine [Batch] Houdini-Engine hbatch
Houdini Engine [Plug-in] Houdini-Engine N/A [open with plug-in]

Note that running hbatch -R will request a non-graphics token. It will not attempt to checkout a graphical token.

The number in brackets indicates the order in which the licenses are checked for a given application.

For more information on running hserver, please refer to the section What kind of options are available to hserver? of the License Management section of the FAQ.
