Hi !  
	I have to create a room in babylon js. I have used 4 plane for the walls and a ground for the ground. With that, we can see all the time on the room because some side are visible and some not.  
	I would like to know if we can do that with some other mesh like ligne. I have to do a grid on the wall and the ground.
 
	 
 
	Tkanks !
