I have a stealth game where I’m trying to measure the amount of light falling on to a character as it moves around a level. First thought was that there might be some sort of blueprint node that would measure this but I couldn’t find one. Second thought was to raycast to get distance from lights but that seems overly complicated and expensive. Other research seems to involve measuring a volumetric lightmap or doing pixel sampling with a 2D scene capture. Everything I’ve found doesn’t happen to have a clear path that I’m able to follow.
Am I out of luck without diving into C++? Has anyone done anything similar?
