Weird texture HOM thing.

[LORDZILLA_2002]

I've been working on this map on and off for the last few months and I recently added a small section where you interact with a computer (some tagged linedefs with a computer texture) and it lowers this section in the room revealing a keycard and a hell knight which are placed on a sector that's raised slightly above the floor... and that sector has a sort of Hall of Mirrors effect for some reason and I don't know how to fix it.

 

I've provided a few screenshots which should hopefully help.

 

The map is in DOOM II format.

Looks like the linedefs around the raised section are missing lower textures.

 

If I'm interpreting your map correctly, you just need to assign back-side lower textures to the linedefs in the inner square. They're not visible when the map starts so DoomBuilder won't flag them as missing - it doesn't know that they will be visible later once the outer sector lowers.

 

Like this:
