Yeah part of the issue is the dimensions of the character model. Since the combadge doesn't seem to be an actual part of the model itself (whereas the clothing actually is), it'll clip through your officer's ***** because they're not designed to bend and rotate in order to match.
Its not, it simply a case of incorrect bone assignments, the regular combadges work because they are correctly assigned bone weights as others seem they just never bothered with them.
Another minor nitpick: The rank insignias on the 7 of 9 Uniform have a minor clipping issue that cause the the Lt. Commander and up pips to be partially absorbed by the collar. Just needs the anchor point re oriented. Thanks!
im getting clipping issues with klingon armour female bare chest and biggest bust possible with a shash over it, same with reman cloak catching on the legs, like the neck size of a toon and certain neck collars on certain uniforms. the combadge clip problem is one of quite a few that hasnt been solved.
