I mean, both things are possible.
Are they? O.o ...How would you get a wall to change texture upon activating a terminal, then?
With replacing 3D entities by script.
But the wall is not an "entity", those are enemies and decorations... Unless you mean there's a script command to replace one wall with another wall...
Um. You're making a 3D model with the size of 1 tile and placing it as usual.
Ah, so it requires 3D modeling... It's a little more complicated than I thought, then.
