I have opentoonz installed as a flatpak app on Ubuntu 22.04.
All I would like to do is to render a scene from the command line. I thought that the following command should work:
/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=tcomposer io.github.OpenToonz scenes/Test.tnz
But this gives me the following error message:
Gtk-Message: 11:26:12.752: Failed to load module "canberra-gtk-module"
Gtk-Message: 11:26:12.753: Failed to load module "canberra-gtk-module"
Qt: Session management error: Could not open network socket
plugin search directory:/home/olf/.config/OpenToonz/stuff/plugins
===== PluginLoadController::finished() =====
Couldn't find the project
The fact that it can't open the project seems to be the issue.
I would appreciate any example on how to properly render a file from the command line.
