Does BluePrints work inside matinee?

Does BluePrints work inside matinee ?
I have the simplest BP:
A trigger box and an actor inside of it.

In the EventGraph:
Event Actor Begin Overlap → Set Actor Location

It works fine in the game but when I
run the matinee it doesn’t work.

Am I doing something wrong ?

You can animate blueprints and set any variable inside them with Matinee as long as the variable is set to Expose to Matinee in the details panel. But it sounds like you are trying to do something completely different since you are using Event Begin Play to set a variable so i’m not sure what the problem is. Can you post some screenshots please?
