Pretty much what the question is asking, is it possible to see SurfaceGui's through walls, just like you can see some BillboardGui's through walls? I was hoping on using this to make a thermal scope. Any suggestions?
Thermal scope huh? Interesting. But I don't believe there's a way to see a SurfaceGui Through walls... Unless you set certain Brick's Transparency to 0.001. You pretty much don't see a difference when you do that.
But as a result, SurfaceGuis can be seen through the Brick with a Transparency of 0.001. Same with SelectionBoxes!
This MIGHT bring lag though. I am not sure, since I haven't comfirmed.
