Map Border Effect

I’m trying to recreate this effect that I saw in Rocket League for my map border effect when players get near it.

As you can see, when the ball is near the wall, an indicator appears on the wall with a grid effect. The grid effect stands still and the circle around it acts as a lens that you can see it with when the ball is near the wall

So far, I haven’t really been able to come up with any good ideas. I was thinking it would be possible to do by placing a ‘SurfaceGui’ on a part and then somehow masking it so that it only shows when the player is near, but I’m not sure how to go about implementing this.
I tried searching for map border effects like this in Roblox but I only found blast barrier borders (which I might consider using in conjunction with this effect).

Thanks in advance for any ideas!

Currently, I don’t think there is really any way to do this that is performant. All I could think of is sort of what you suggested, with SurfaceGuis.
