Using custom textures/sounds

[{dFb}eMac]

How do you go about using custom textures and sounds in UT3 for mutators? In UT99 and UT2k4 I used the #exec compiler directive but it doesn't seam to exist in UT3.

I've also created a .upk file in UnrealEd but when I do something like SoundCue'UPKNAME.SOUNDNAME' I get a "Unresolved reference to SoundCue" warning when I try to compile. I've tried placing the .upk file in several different folders.

Thanks!

Placing the .upk in Main UTGame > CookedPC works for me... But,

This is my situation:
I have made a gun with custom sounds and textures 'materials' rather. When I load the weapon in game, the Gun texture is missing and there is no sound.
0 Errors and 0 Warnings.. and all textures materials sounds and cues referenced.
