cant get it to work, trying to compile an stg44, should be a rather simple question...

Decompiling gives something like this

$texturegroup skinfamilies
$origin
{
{"v_mp44.vmt"
"v_hand.vmt"
}
{"v_mp44.vmt"
"v_hand.vmt"
}
}

I think you need to recompile with something like

$texturegroup skinfamilies
$origin
{
{"v_mp44.vmt"
"us_sleeve.vmt"
}

{"v_mp44.vmt"
"v_axis_sleeve.vmt"
}

{"v_mp44.vmt"
"v_hand.vmt"
}
}

It's something like that i'm not sure exactly.
