Overlapping Blockers and raising Platforms

Hey, I'm trying to make this super realistic town and stuff, but I have a few problems. I turned my stone walls to no pathing texture so I could connect them and then I put pathing blockers on them so noone could walk through. My problem is though I want to put visibility blockers on the walls too so people cannot see across them. My other question is I'm trying to make a house with a stairway that goes up to it. I used tables and raised each one ever so much but I cannot figure out how to get invisible platforms to raise. I tried the destructible - Raise Elevator level and that didn't work. Please help! :(

For the invisible platforms, just use CTRL + PGUp/PGDown.

Have you tried the line of sight blockers? i never tried but im about sure it will work

all u need to do is make the tables walkable and no elivator is needed

I did do that but he just walks through them not on them, and Yes ive tried line of site blockers but I'm trying to find out how to put line of site blockers on pathing blockers.
