Hey guys. I’m looking to find out if there’s an efficient way of creating (or faking) dynamic GI bounces when using a flashlight with the player. I’ve been through numerous posts on the topic of dynamic GI and LPV, and it seems as if you can only use it through a directional light. Apparently using a spotlight for LPV GI provides too much of a hit to performance. I’d love to be able to create it in-game somehow, or at least fake the GI in a way.
As an example of flashlight GI, I looked at The Last of Us, which as far as I know isn’t true dynamic global illumination.
