Is my Actor lit by a specific light?

Development Programming & Scripting Blueprint

Hi,

my question is simple to ask:

Is there a way to find out, if an actor is lit by a specific light?

Not in blueprints anyway, you could fake it with a trace though it could be expensive depending on what you want to achieve here. Look into doing a line trace from your light’s location to the actor location, if it hits then the light is hitting the actor i.e. not being blocked by anything.

Yep line tracing would be the way to go, doesn’t work so well for global illumination though but you can see if it’s in line of sight of a light source at least.
