Nothing to interact with.

I just installed this and there is nothing to work with.
The only thing I can do is drag in GetVariables or controller.
However controller is only a 1 way in and no output.

Regenerate your nodes. Project Settings → Visual Scripting → Regenerate.

Every time you add a script you will need to do that. You will also find all your other assemblies and nodes there that aren’t in the default types.

Add what script?
I didn’t see anything in the tutorial video they made about adding a script.
I thought that was the whole idea, to not need to script.

Did the regenerate fix the problem?
