[Project Files] Unreal Flash Light with Light Function
Added 2020-08-13 17:44:50 +0000 UTCpassword : codelikeme_flash
Today, I am going to implement a flash light with a light function for the unreal first person template. A light function is a material that can be applied to a light to filter the intensity of the light across the projection. When we project a real flash light onto a surface, the light intensity is not uniform on each point of projection, we can see some artifacts such as bright spots in the middle and sometimes rings, lines..etc on the projection as shown in the thumbnail. We can use light functions to achieve that effect.
