CHANGE_TEX

Usage:
CHANGE_TEX <surface> <new texture> <map tag>

Description:
Use this to change textures.

Details:
<surface> is what surface we want to change.
Allowed values are:

• FLOOR
• CEILING
• SKY
• RIGHT_UPPER
• RIGHT_MIDDLE
• RIGHT_LOWER
• LEFT_UPPER
• LEFT_MIDDLE
• LEFT_LOWER

<new texture> is the texture or flat we want to assign (Note that in EDGE flats and textures are interchangeable).

<map tag> is the line or sector tag in your map editor.

Useful mostly for special events, like making the sky change from day to night, making a TV that is switched on or off (or shows different programs), special animations, etc.

Also, you can only change one surface texture at a time. For example, if you want to change an entire right side of a wall (upper/middle/lower), you must use three different entries. Same if you want to change the ceiling and floor, you'll need to use two seperate entries.
