Afraid not. OBB is an external library that was never touched for almost a decade. Thus a modification is not really easy. It's on our list, but for the next time you must live with it.
I have another question, jcl. Will you add additional shapes (or at least one more - capsule) for OBB library, if we will collect enough votes for it over the forum (let's say). The reasonы why I ask this now are:
1 - community members kept asking for this for a quite long time and kept on ranting that OBB with only elipsoid doesn't fit their (our) needs;
2 - now, when you said that it's just an external library which wasn't really ever touched, I understand (at least I hope so) why you refused to add another collusion shape back then. Probably cause it didn't really seemed to be worthy messing around with external library which works as it is (out of the box), but now you, when you are going to look for that BUG I've reported and going to mess around with that library anyway, maybe there is a way to add one more collusion shape, to satisfy US (community members, which still help to keep Acknex undead)? We could do a vote, to see if people are in need of one more collusion shape (CAPSULE).
Best regards
