I want to configure Screen percentage for Planar Reflection, but didn’t see a way to do it through blueprint. Therefore, I created another component, and through Blueprint I switch the visibility of these components. However, there is nothing to be done. When switching visibility / activation or Actor Hidden in Game, nothing changes. Components remain inactive, but continue to work in the background.
I found a solution:
You must use Set Visibility with Set Hidden in Game from Planar Reflection Component.
