I feel stupid. I just found DynamicLightEnvironment.ForceUpdate(). I’m going to take a look at that.
Edit: Nevermind. It turns out that function doesn’t do what I hoped it would do. I think it reattaches a component to its owner. But it doesn’t seem to solve my problem.
Edit 2: And DynamicLightEnvironment.ResetEnvironment() doesn’t seem to fix it either. Maybe something else is going wrong.
