A mapmodel entity is placed at a z-coordinate that is based on the floor
height of map geometry and a z-offset. The z-offset is a sum of the
entity attribute 3 and the third mapmodel slot parameter. The entity
z-offset can range from 0 to 255 while the mapmodel slot parameter can
be any integer including negative numbers. So, to place a mapmodel below
floor height, the mapmodel slot parameter has to be negative.
This script decreases the mapmodel slot parameter by one and increases
the z-offset of every mapmodel which uses that slot also by one. This
means, that all mapmodel are exact in the same place afterwards - but
the entity z-offset now has room to lower the mapmodel by one more cube.
The script requires one parameter: the mapmodel slot number.
If you need more z-offset available, run the script several times.
