Using the green question mark discs in Content Examples?

I know this is probably a dumb question, but how do I access or use these little spinning green and white question mark discs in the Content Examples? I assume they pull up some information in some way. I can’t seem to find any list of controls for playing or launching any of these Content Example Maps. I would like to interact with everything as intended.

Thank you.


If you select the question marks, which are known as Documentation Actors, in the viewport, you will see a button appear in the Details panel called Open Help URL. Clicking this button will take you to relevant documentation on our website.

OK, so its not something to interact with in Play or Simulation mode then.

Thank you for the reply.

I know this thread is old but, the green question mark discs all link to the generic page about the Content Examples sample project which also indicates that this project is updated for UE 5.

The links, for example: Resources/ContentExamples/Lighting/1_3 no longer work which makes the Content Examples sample project virtually useless.
