Hello, so im trying to make it when my AI walks or gets near a light source(fire), it’ll extend his Sight so he can see out further since my game is during the night. ANY help would be great.

The simplest solution will be creating lit areas manually(through collision boxes). Binding ai sense and brightness of the area in the way human see can be extremely difficult.
