Hey Folks, so I’ve been trying to figure out this Eye Adaptation. I’ve been tasked with reverse-engineering some Rain FX for our project and this one node is throwing me off. We’re trying to increase the rains visibility while retaining the EyeAdaptation.
Some believe it’s set up correctly (Image 1, “Sector 1”), but I don’t understand what’s happening. I tried searching for information on it, but I’ve come up empty.
The goal here is to have the rain brighten in darkness, and darken when its bright. It looks like no-one uses EyeAdaptation within the material, since its globally applied through Auto-exposure.
The documentation here is for PostProcess. https://docs.unrealengine.com/latest/INT/Engine/Rendering/PostProcessEffects/AutomaticExposure/

How can I establish the range for Eye Adaptation if possible?
