[Need help] Md3.cfg problem

[a_slow_old_man]

Hello fellow cubers,

I have encountered a problem while setting up the md3.cfg for a weapon mod.
I used a alpha channel and copied the commands out of Toca's window mapmodel. It didnt work, the whole object was invisible.

After that I changed the "mdlalphatest 80" to "mdlalphatest Cube 1" as suggested at a sauerbraten website.
But the whole model changed to black. The texture as well as the transparent part.

Do you know how I can fix that?

Thanks in advance :)
