Change an actor size on client-to-server side using a variable from PlayerCharacter

But if I want to increase the number of actors instead of just 1 cube, wouldn’t that be not pratical to do everything in the CharacterBP?

Also I’ve changed the cube blueprint to change in a fixed value from a variable in the cube itself and it works just as expected. The client overlap the trigger box and changes the variable on the server, making it visible on both sides.

I think the problem is that, when pressing the “Z” key to change the characterBP variable “MicLoudness”, the client side is not sending the information for it to change on the server side, correct? Shouldn’t that work since I’m using a CustomEvent to change the characterBP variable which is set to “run on server”?
