Can I paint one wall?

[Glenn Woodward]

I hear what everyone is saying about the Material Painter and the appropriate warnings as to it's use.

BUT...there is a way to use the Material Painter and paint only 1 wall in a room.
The trick is to temporarily name the room as an external room type (porch, etc), use the Material Painter to paint 1 wall and then rename the room to back to what you want.
