Visibility fade for an object?

Hey everyone!

I want to create an effect where if object leaves a certain area (like an island) its visibility would fade and it would become completely invisible. Same with it re entering that area where it should become visible again.
How one would be best to approach this? Thanks for any tips or ideas!

depends on how complicated the shape of the certain area is…if it’s a circle or square or something easy you can just use overlaps and trigger boxes/spheres…when the overlap begins or ends tell the Blueprint actor with this translucent materiel to start the Timeline fade out/in…
If it’s like a real island with a ton of twisting corners and just way too much to mark the edges easily than something like a line trace down to see what material is beneath it or what actor it hits and if it’s say in the ocean then fade…
I’m sure there’s a few other ways to do this too but you’ve some options…

Thanks for the reply! Its really just like an island. Pretty much a round shape so very simple. Will try with animated material.
