I have an emissive material which is quite bright and often occupies space in the user’s viewport. This results in that eye adaptation frequently makes the scene far too dark, almost to the point of eye strain.

Is there a way that I can exclude this specific material from affecting eye adaptation? It is a post processing material, applied as a blendable on my post processing volume which appears when rendering actors in custom depth.

I’m interested in this too. Someone? I have an outline material for focused objects used on Post Processing. But, if its dark (night or inside) and I use some color like orange, the scene is completely dark because Eye Adaptation.
