Bind an Actor Property to a Variable?

Development Programming & Scripting
1

This might not exist as a feature at all, but I don’t know how to search for it.

I have some Lights and Fog in my scene that I’d like to be able to adjust the colours for simultaneously.
Obviously one way to do this is to Get All Actors of Class/With Tag, Cast to the components, and set the variables that way. But it’s a big faff.

I was wondering if it is possible to essentially link Colour Properties of these actors to a variable (such as a Collection parameter) that simply updates when the variable does, similar to binding in UMG. Or Materials updating their colours based on a Collection Parameter.

You have multiple way to do that, but no auto-binding.

Dont do get all actor + cast on a tick but cache it on the begin play (or something like this),
Then, change your color by a function like void ChangeColor(FLinearColor Color) who will also change for the fog and everything you want.
