I’m trying to figure out how to make a light look like it is coming from the face of an object while still lighting up an entire area. The best example I can come up with is this:

But I cant find what this method would be called. Anybody know?
It’s called just put a point light inside the object. (Or if it’s a long object, put two point lights inside it.)
There’s lots of stuff you can do in theory with real time global illumination but if you don’t already have a general idea how that works, forget it, implementing that in Unity is going to be way over your head, and it would probably not be worth the cost to framerate anyway.
You can also fake lighting effects in certain situations by just using an additive texture that you fade in or out depending on how close it is to the source; depending on what you’re doing that might work better than lots of point lights.
