Basic Raytracing Help

Hello! I am fairly new to the blueprint visual scripting language but have a decent understanding of programming in general, as well as of what I’m trying to accomplish. Here is what I need help doing: I want to shoot a ray from the camera on the forward vector, get the object it hits (and its material), for the period of time that that object is in the ray it will glow, and by clicking at that moment, it will change glow color (multiply emission values of material with scalar parameter)… emission values are simple, I just need a way of getting the object, and sending a message from the blueprint to the right material… Thank you in advance community!!!

You’ll want to look into using traces (Raytracing is a different thing).
