After two hours of trying to perform a simple task, I’ve decided to come here. I’m trying to simply make existing light blueprints change their color whenever I want them to. I made a Blueprint Interface and implemented it into the lights. I added the event I needed from the Interface with no problems. Then, I wanted to trigger that event from the Level Blueprint. I implemented the Interface into it, but none of the functions interacted with the lights in any way whatsoever. It turns out I can replicate this problem in brand new projects. Below is the exact process I followed in an attempt to try and make this work somehow. Sorry I couldn’t embed any of them, I was having trouble with inserting an image I forgot to add.
