: 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.
I will try this, thank you all very much (if it works). It will save me a lot of texture problems where the textures covering the secret terminals do not match up with the walls beside it.
