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Is ist just that everything is outdated for Unreal5?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.

craig422 · January 20, 2023, 4:38pm

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

craig422 · February 2, 2023, 2:58pm

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:

paulgolter · February 8, 2023, 12:12pm

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.

Ricardo · February 28, 2024, 1:12pm

First of all, thanks for sharing all the information on the forum.
I am on the same page that you @paulgolter

I have been trying to follow the instructions on the link:
https://github.com/ue4plugins/tk-framework-unrealqt

I tried to use the git descriptor on the framework. When Shotgrid tried to download v1.3.0, the file was not found. ( I used tank cache_apps to process the frameworks)
tk-framework-unrealqt_v1.x.x:
location:
version: v1.3.0
type: git
path: git@github.com:ue4plugins/tk-framework-unrealqt.git
I tried to use a GitHub_release descriptor on the framework. The v1.3.0.zip file was not found. ( I used tank cache_apps to process the frameworks)
tk-framework-unrealqt_v1.x.x:
location:
version: v1.3.0
type: github_release
organization: ue4plugins
repository: tk-framework-unrealqt
The only part that I didn’t do was run the build script because I didn’t have any idea how can I run it. Another important information is the current framework which is 1.2.3. Unfortunately, is the only pack that shotgrid loads.
tk-framework-unrealqt_v1.x.x:
location:
organization: ue4plugins
repository: tk-framework-unrealqt
version: v1.2.3
type: github_release

Could you guys help me, please.

Only the framework v1.2.3 was located. The framework version 1.3.0 could not be located. What is wrong?
What are the steps to run build_packages.sh ?

Maybe there is an easier way to integrate Unreal 5 on Shotgrid that I don’t know.

I’m all ears.
Thanks a million
Ricardo

Ricardo · March 6, 2024, 11:24am

Hi Guys

I tried to use the tk-framework-unrealqt_v1.3.0, but it doesn’t exist…
The instructions were weird for me…

The solution I came up with was to change the frameworks to v1.2.3, use the tank to update frameworks and cache and install Pyside 2 within the Unreal App.

  # unrealqt - PySide build for Unreal
  tk-framework-unrealqt_v1.x.x:
    location:
      organization: ue4plugins
      repository: tk-framework-unrealqt
      version: v1.2.3
      type: github_release

I enabled the Shotgrid, Python Foundation Packages and Python Automation Test Plugins into Shotgrid.
I Installed Pyside2 within the Unreal App.

run cmd as Administrator

cd "C:\Program Files\Epic Games\UE_5.3\Engine\Binaries\ThirdParty\Python3\Win64"
python.exe -m pip install --upgrade pip

cd Scripts
pip install pyside2

I loaded Unreal through of Shotgrid App. Done.

Thanks

Francesc_Macià · March 6, 2024, 12:16pm

Nice @Ricardo , and the Published is working?
Because I just make it work the “Loader” but is failing on the publish.
Thanks

You may have to check what you are selecting, this is your error, basically the hook is trying to gather info in a property that does not exist.

Just be aware that the Unreal API can change between versions.

scottballard · April 2, 2025, 9:38pm

Thank you and everyone else on this thread. I was pulling my hair out trying to figure out why I couldn’t get SG to load in Unreal.

The resources\build_packages.sh -b command did the trick! There really should be something on the GitHub - ue4plugins/tk-config-unreal: Unreal Integration based on tk-config-default2 repo about having to run that.
