: Okay, I've never done this but I know how. You take an adjacent ceiling, or
: floor, elevation and put a terminal on it. Then, you adjust the elevation
: so that the height difference is imperceptible, but still there. ( 0.001
: Maybe?)
First the ceiling must be no larger than 1 wu above the floor level. I think this will be no problem for PID. =)
What you do is to create a rectangle and elevate it above the floor level, and lower it below the ceiling level.
Texture the sides with the terminal texture (you'll see that the terminal menu won't pop up unless you texture the elevated area and the lowered area)
Now we've created a working terminal, that looks outright ugly. The last step is where the magic occour. Simply lower the rectangle back to the main floor level and the main ceiling level so nothing of it will show.
voila - you're done.
