Live Characters and false joint rotations

[Vaquero]

For anyone who may encounter similar problems: 3DS Max has a Z-up axis coordinate system and many other content creation suites have a Y-up axis, such as Maya and MotionBuilder. So when importing files to 3DS Max, it applies a 90 degree rotation to the objects. That might mess with the Cal3D export and the Live Characters plugin, I guess.
My solution to solve the issue was to add a root bone to the skeleton.

Hey! Unfortunately I still have problems with the Live Characters plugin and custom characters. Why is this happening and how can I fix this? The character looks okay in any other program, but using Cal3D and the Live Characters plugin for MotionBuilder it gets crippled inside Vizard.
