Context:
Similar to parameters in the Material editor, PCG Graph Parameters are user created overridable values and can help create customizable graphs for a variety of situations.
Problem:
The licensee has encountered issues with overridden graph parameters in PCG components. When attempting to copy a PCG component with overridden graph parameters, those parameters are reset to their default values.
1.) Create a new PCG Graph asset.
2.) Add some input parameters to it and save it.
3.) Create a new Actor Blueprint and add the PCG Component.
4.) Set the Graph in the PCG Component to the newly created PCG Graph asset.
5.) Place an instance of the above Blueprint in the level.
6.) Select the PCG component on that instance and override any parameter.
7.) Copy and paste the PCG component: the overridden parameters on the new component are reset to the default values from the PCG Graph asset.
Additionally, a repro project has been provided.
1.) Open L_Test level
2.) Select BP_TestActor in Outliner
3.) Copy and paste PCG component in details panel
4.) Component PCG1 now has all the parameters reset to default values
Observe: Overridden graph parameters in duplicated PCG Components are reset to the default values from the PCG Graph asset.
Expected: Overridden graph parameters should be preserved when duplicating a PCG Component.
