Packaging for Windows fails when Optitrack Livelink Plugin enabled on UE 5.3

I am working with unreal 5.3.2 and and the optitrack Plugins:" Unreal Engine 5 Plugin 5.3 v1".

I want to adjust the View Point in my nDisplay Cave according to the optitrack position of the Head. However, as soon as I enable the optitrack- Live Link Plugin, the packaging process for Windows fails. Everything seems to work in the editor though. In the Logs, I found this:

Code: Select all

UATHelper: Packaging (Windows): Expecting to find a type to be declared in a module rules named 'OptitrackLiveLink' in UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null.  This type must derive from the 'ModuleRules' type defined by Unreal Build Tool.
UATHelper: Packaging (Windows): Took 1.53s to run dotnet.exe, ExitCode=6
UATHelper: Packaging (Windows): UnrealBuildTool failed. See log for more details. (C:\Users\<Username>\AppData\Roaming\Unreal Engine\AutomationTool\Logs\D+UnrealEngine+UE_5.3\UBT-NDisplay-Win64-Shipping.txt)

In the mentioned file, there is the following BuildException:

Code: Select all

BuildException: Expecting to find a type to be declared in a module rules named 'OptitrackNatnet' in UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null.  This type must derive from the 'ModuleRules' type defined by Unreal Build Tool.

Is this type something I have to declare myself? I didn't find any documentation for this.

Thanks a lot for your answers and best regards

Edit: I was able to find a workaround. Apparently this problem only occurs when the plugin is installed globally. If do it in the Project specific plugin folder, it works.
