<p style="margin: 0.1rem 0; line-height: 1.0;">That is easy, take another look. </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">Euler angles are not listed anywhere! </p>
<p style="margin: 0.1rem 0; line-height: 1.0;">Convert to axis-angle like showed in Part 2 and forget xyz angles/</p>

<p style="margin: 0.1rem 0px; line-height: 1;"> </p>
Apparently BVH uses degrees for rotations. Units for HAnimMotion should use radians unless otherwise specified in a UNIT statement, AFAIK.
