Important

Pixyz Studio 2025 still features a Python API interface, enabling developers to extend its out-of-the-box capabilities, but with the following limitations compared to previous releases (see What's New):

  • It is no longer possible to import and export using scripting (the IO module is removed from the API), nor to reset or load a .pxz scene.
  • Pixyz Studio plugins are compatible with Pixyz Studio only, and cannot be run with Pixyz SDK.
  • The PyQt native support was discontinued, so plugins are limited to what the XML structure can offer. Users wishing to create advanced interfaces should use the full power of Pixyz SDK.

Also, a lot of changes have been made to the Python API (functions signatures, behavior,...). Take a close look below to help you migrate your old Pixyz Studio scripts and plugins.

For support, contact Pixyz support or reach out to the community on the Pixyz Forum.
