Failed .bvh file upload

I create my own .bvh files, but when I go to upload them, SL ignores the position, and only uses the motion.
For example, if I created an animation were an AV was sitting down, indian style, while slowly shaking his head back and forth, SL will only upload the head movment, and I end up with an AV that's standing, shaking his head x-x.


Any ideas what the problem is? The files I create work fine on my end when I test them.

Is frame 1 set to the default T pose? If so, make sure you adjust every body part at least slightly in frame 2; otherwise you get unexpected results. Also, make sure you 'scale automatically' when exporting to BVH (if you're using Poser).
