No you don’t.
The above reply seems to be AI generated and somewhat misleading.
The reason the brightness is changing is because you’re creating an entirely new Post Process Settings struct and passing it to the Post Process Volume. So everything except the settings exposed on the node will get reset to the default value.
So to fix that, instead of using the “Make PostProcessSettings” node, use the “Set members in PostProcessSettings” node. That way only the settings you want to modify will get updated, the rest will stay the same.
