Shotgrid with Unreal Engine 5.1

paulgolter · January 19, 2023, 4:56pm

Hey everyone,

I want to setup shotgrid for unreal engine 5.1.

So far I integrated all the required changes from:

In to my config to the best of my knowledge.
I enabled the Shotgrid plugin for my unreal project.
But there is no Shotgrid menu or anything in sight when I start Unreal via Shotgrid desktop.

I use this config entry in in env\includes\settings\tk-multi-launchapp.yml to add the Unreal starter.

settings.tk-multi-launchapp.unreal:
  engine: tk-unreal
  icon: "{config_path}/icons/unreal_editor.png"
  windows_path: "@path.windows.unreal"
  linux_path: "@path.linux.unreal"
  menu_name: Unreal Engine {version}
  location: "@apps.tk-multi-launchapp.location"
  versions: ["5.1"]
  hook_before_register_command: "{config}/tk-multi-launchapp/before_register_command.py"
  hook_before_app_launch: "{config}/tk-multi-launchapp/before_app_launch.py"

Is ist just that everything is outdated for Unreal5? Can anyone share some experiences maybe?

All the best

Have you added an entry for it in the software table?

Hey @craig422

After a while I got it to a point in which the engine properly loaded and the shotgrid menu appeared in unreal. I am on to the next error now, it seems to have trouble to import Qt.

Excerpt from the unreal python console:

I am not exactly sure why it is not able to import QtWidgets from tank.platform.qt5.
This import works in other softwares like maya or blender without a problem.

You need to load the framework tk-framework-unrealqt

unrealqt - PySide build for Unreal

tk-framework-unrealqt_v1.x.x:
location:
version: v1.2.3
type: github_release
organization: ue4plugins
repository: tk-framework-unrealqt

needs to go in frameworks.yml

craig422 · January 20, 2023, 4:42pm

Just to let you know that UE5.1 does not work with Shtogrid presently, there are multiple changes to the Unreal prython API that have broken this integration. Looking at bugfixes on the unreal site I believe many of these are addressed in upcoming 5.2

It works great on UE5

paulgolter · February 2, 2023, 10:49am

Hey @craig422

Sorry for the late respose, was away for a while!

Thanks for the note about the framework settings with tk-framework-unrealqt
I already had them in place tough.

I see so Unreal 5.1 is the problem. Are the unreal python api changes you were talking about adressable by updating the shotgrid unreal toolkit? (Could you go a bit more in to detail what is breaking there exactly?)

Or do we have to wait for the new unreal release?

All the best

I just tried it with Unreal 5.0.3 and I get the exact same error as above:

I think you need to wait as there are aspects that need fixing in the next update that can’t easily be fixed in the SG integration – You can of course use 5.0

paulgolter · February 2, 2023, 5:09pm

Ok I see!

I tried using 5.0.3 as you can see in the above message and got the same errors. You know by any chance whats going on?

craig422 · February 2, 2023, 5:49pm

It does look like a qt issue and I’ve had a similar error when this framework has not loaded correctly. Have you read the documentation here https://github.com/ue4plugins/tk-framework-unrealqt ?

craig422 · February 2, 2023, 5:53pm

PS You need to make sure you’ve changed the bootstrap.py hook or it won’t load:

Hey @craig422

Thanks for pointing me to the README.md file of the tk-framework-unrealqt project.

I realised I never executed the build script in:

resources\build_packages.sh

After I executed it once and the again with the -b option unreal could finally import the qt library from the newly created virtual env.

And it even works in Unreal 5.1 for me.
