Yeah, that's it! But I still can't get the transparency to work correctly, i.e. at all, though I'm using proper transparency maps. Those are supposed to be the sting to all this, for I'm trying to create authentic eyebrows. I created them by cutting out the brows from the original face and saving them as *.obj. Is there anything that has to be considered while making them (I already did all the usual stuff -> UVMapper etc.)?
