Change Material Scalar Parameter Only On Client?

Hey people !

I’m working on some kind of highlighting for “interactable” objects in my game (think Thief Deadly Shadows style highlight…).

So my actor is set to replicate… it needs to be because it’s in a multiplayer setting. I’m setting up a dynamic material instance in the construction script. I call an event in game for my object to highlight but my material is rendered with the new scalar param on both the server and the client. Is there a way, using only Blueprints, to change a material’s scalar parameter only on the client side ?
