Mapping Help needed (Textures above tunnels)

[Bukz]

...I'm hoping I don't understand the question because there is no way you don't know how to do that. Look up, hold x, scrollwheel.

Just tried. all that happens is the height of the wall goes up. it does not change the texture.

Mael is right, this should work. It is also the most efficient method of altering textures. (imo) The only thing I can think of is that you have key "x" bound to something else.

Try entering:

[cubescript]/bind X [ if $editing [ domodifier 3 ] ][/cubescript]

...into the console and see if it works then.
