I did that the first time I used this hud, still/never worked. Where exactly would I find the hud menu anyways?
It's not on the main menu, and it doesn't show ingame (I checked the HUD tab on the esc menu, it's the same
)
Sounds like a really neat idea, anyone else have trouble with this? Btw, when you mean GPP folder, do you mean C:/Program Files/Tremulous (Windows XP), or C:/Documents and Settings/USERNAMEHERE/Application Data/Tremulous (Windows XP)? I placed it in the installation folder (Program Files)
Sorry for being a noob 
Naah, it's fine.

If you installed it correctly the menu should show up in the main menu.
You could place them in your applications data folder and it should work, but here I just put them into the install directory.
You should put the z-hudoptions.pk3 file in into the same folder that has the "data-gpp1.pk3" and "vms-gpp1.pk3" files in it.
Then you put the "ui" folder into the very same folder ("gpp"), so the directory to, lets say, default superpie hud, should be:
C:/Program Files/Tremulous/gpp/ui/Default/Superpie1.cfg
and the link to z-hudoptions.pk3 should be:
C:/Program Files/Tremulous/gpp/z-hudoption.pk3
Hope this works, the problem of it not showing up should be that you put the files into the wrong directory.
If this does not work, I don't know what the problem is.

...This should still work though :3
