Launch hooks in a Studio Addon

Yul · 7 July 2025 09:42

Hi,

Is there some doc on how to code a custom launch hook (pre-launch, or post-launch) inside a Studio Addon ?

The only doc I found does not contain any example :
Launch hooks

It’s easy to add a pre-launch hooks inside an existing addon, because we can copy an existing hook.

But how to have such a hook in a Studio Addon ?
I guess there is something to override, to have the hook found and triggered (similar to what does get_publish_plugin_paths for publish plugins).

You can specify the hooks location in the addon.py

github.com/ynput/ayon-houdini

client/ayon_houdini/addon.py

9bc027ea6


      
          def get_launch_hook_paths(self, app):
              if app.host_name != self.host_name:
                  return []
              return [
                  os.path.join(HOUDINI_HOST_DIR, "hooks")
              ]

Additionally,
here’s an example hook set_default_display_and_view.py that shows how to access studio settings.
