.Map :: MoHAA Mapping

how do i make it so that only the part of the brush that is seen has a texture

and make so that only the room your in is drawn and not the whole map

Only one face will be highlighted if you hold down Ctrl and Shift.

If you put "portal" brushes in the doorways of a room without windows, the rest of the world is not drawn.

sounds good how do you make portal brushes
