text input in my HUD blueprint for the
stream URL and link it to the texture
actor blueprint within the level
blueprint
These 2 are not the same. Above you mention an actor, below the Level Blueprint (that has that actor)
from the HUD to the level blueprint.
I’ll assume that we need to talk to the Actor in the LB as I feel that’d be more desirable here. Do correct me if I’m wrong, though.
If you want something ham-fisted, you can Get All Actors with Tag (after giving Texture Actors tags) or, Get Actor of Class if there’s only one Texture Actor.
There are more nuanced methods, registering a dispatcher, for example. I may be able to suggest something more tangible but you’d need to tell which blueprint creates the widget.
