@richard60 I don't mean to imply my mockup would have Poser attempt to guess mapping; it depicts a user in the middle of doing the mapping. The element with '[None]' is a user choice where there's no possible equivalent value and the element with 'Choose…' is one where the user hasn't yet selected an equivalent or '[None']. I agree that Poser shouldn't guess. The main reason I'd prefer this be dynamically translated is because there still exist body parts where there's no consistently followed naming convention (e.g. jaw, lowerJaw) and a static search/replace on a BVH file leaves you with the same problem the next time you try to apply that BVH to a new figure where yet again the body part has a different name. Make BVH import as transparent as possible.
