walk through walls

[whoisit]

As a newbee in the world of editing, I've been trying to create sections of walls where you could walk through and enter a small room (but not see the room from the outside) to pick items up. I can't figure it out, please any advice would be greatly appreciated. Thanks

Build the secret room as usual, but in the spot what the secret "wall" should be, use a sheet brush. You won't be able to see through it, but like all sheets, you'll be able to walk through it. Texture it like the rest of the wall.

also, you might want to select 2 sided on the sheet brush's texture properties so it looks like a wall from the inside
