 Anything purely blue in a { Texture, turns invisible when you tie it to a func_wall entity with solid render mode and 255 render amount.
 
 Invisible:   Make a '{blue' textured brush, Tie it to entity (Ctrl + T) make it func_wall, Render mode Solid, render amount 255.
 
 ladder: Tie it to func_wall with render mode: solid and amount: 255
 
 Half invisible like glass:  Make a brush, tie it to a func_wall entity set render mode: Texture, Amount: (depending on how visible u want it) 150 is fine.
