Trigger volume and Blueprint actor

[Xenosis]

Hello

How can I get a trigger volume in my level to trigger inside a blueprint actor?

I have in my level a trigger volume toggling the visibility of a bunch of spotlights in the level blueprint. But my lamp models uses a emissive material that needs to be changed, when the the player is overlapping the trigger volume and turning off the lights…

So I found this tutorial:

Intro to Materials: Dynamic Material Instances cont. | 10 | v4.0 Tutorial Series | Unreal Engine

But I can’t add the trigger volume in my level to the blueprint actor?

It works fine with a trigger inside the blueprint like in the tutorial:

When you overlap the trigger volume, Cast to your lamp blueprint and call an event/function within.

Are there any tutorials on how to do this?

I can find “cast to Lamp_BP” in my level blueprint… But don’t know what to do then?

No tutorials on how to do this?

Make sure your Lamp_BP have a BoxComponent as a trigger I call it “box1”

The steps below are all done in Level blueprint

When you cast to Lamp_BP then :

Thank you for your reply…

Sorry I’ve just started working with blueprint and I’m confused about doing this…

I don’t think I’ve done it right, getting a blueprint error…

You do not need to call overlap event again, because the Custom Event has been made to handle box1 overlap event, you only have to do is DO WHAT HAPPEN WHEN OVERLAP, you can use Print String for test

I think what he wanted to do is call a trigger box to a actor blueprint. not a level blueprint.
