I want to repeatedly spawn and destroy Unity planes (3D Object) using nodes.

I tried Spawn Prefab, Activate Object, Is Visible, and Object Visible.
All have the option to select a Prefab, but when I click on the drop down menu nothing happens, so I can't select a prefab.
For the Activate Object node- Object>Actor, I can't select an object in the Object drop down menu.
Actually none of my dropdown menus work. Eg. Play Sound: Actor & Audio Clip.

Which way do you think is the best way to continuously enable and disable a large number of Planes throughout a level (for performance)?

Game Object Manager Component using Variables to control whether or not they are active or not sounds like the way to go.

You can use a 3D Object as a source and it will be activated or deactivate depending on the variables set.

To be able to spawn prefabs in your event, you need to add them to the Event Settings node to have it available in the dropdown. There's a Prefabs foldout available to add multiple prefabs :)
