Thanks for your answer! The tutorial looks promising, but first i have to get it to work with one material and one actor (There is only one static mesh in that level)
I am able to “fade in” a actor (Material Fade1) whenever a spefific key is pressed. Do you have a idea how to apply this effect to Event beginplay and not a key? So the actor gets faded in whenever i stream the level in which the actor is located.
