Thanks @3dRaven - It is getting weirder… your GameCharacter doesnt work for me if I edit the default blueprint from the content browser… but it DOES work if I drag an instance of the blueprint into the scene!!! My other actor also works if dragged into the scene.

So the issue is you cant edit the User Parameter on a Niagara System Component created in c++ on the Blueprint class.

But you can edit edit the User Parameter on a Niagara System Component created in BP on the Blueprint class !

And you can edit the User Parameter on a Niagara System Component created in c++ on the Blueprint in the scene!

@3dRaven If possible, can you verify editing the component defaults in the blueprint class from the Content Browser doesnt work for you?

[edit] Even weirder, I can right-click copy the broken User Parameters and they are there. It looks like the drop-down arrow must be broken somehow when editing the class default version.
