Hello I was using bonehumanfootright and I noticed that in the CS it is the Left one .... then I checked the BSA and exported and it is correct , but in CS shows up as left foot ... I then exported the right foot in the clutter bones folder and refreshed image but still shows up upverted as a left foot instad than a right ... I am clueless now someone can give me an explanation?

I would love to help, as I would love to know more about this particular area. Sadly, I know next to nothing about the NIF format. I heard someone say there was a way to remove the extra data that handles slanting feet and lower legs on inclines, and assign the foot portion of the NIF high inertia, friction, and gravity, to keep a humanoid stationary on a moving platform (moved by collisions), however I have absolutely no idea how to begin to become educated on how that could be done either.

Best of luck to you though. I feel your pain; sometimes my awesome modding endeavors feel like dancing with two left feet! XD

At least I know scripting pretty well. =P
