%%%The BVH exporter options contain a checkbox "Root Transform Only". This is a confusing label, as the transformations of other joints are also exported, even when this checkbox is checked. It seems to control whether the translation of the non-root joints is exported.

Rotations are also transformations, hence the confusion.

Even when the label is changed to "Root Translation Only" it is confusing. It can be understood as "for the root, export the translation only", which will be wrong as the rotation of the root joint will always be exported.

I'd suggest "Store translation only for root joint", or "Store only rotation for non-root joints".
