Making a door is a simple process, but may also be one of the first obstacles a person new to Doom mapping runs into. Suppose that we have a map similar to the one shown on the diagram to the right, with two rooms connected by a hallway. Sector A is a first room, Sector C is the second room, and Sector B will be our door. Start off by lowering the ceiling height of Sector B to be equal to that of the floor. For example, if your floor height is zero, make the ceiling height zero as well. Make sure to apply upper textures where needed. * Back to the editing index
