Added a script for adjusting forward throw target anims in Blender. Snippet is pretty long; if you have a better idea of formatting it or putting it elsewhere let me know.

Scenario: you load two characters into Mod Tool and rotate (+/-180°) the throw target character because you need them to stand face to face as you work on an animation. When you are done animating, the target animation would need to be reversed again. This means multiplying the velocities by -1; the rotation also needs correcting. So it looks like you need *(-1) for the x rotation and -/+180° (depending on your initial change) for the y rotation. | Scenario: you load two characters into Mod Tool and rotate (+/-180°) the throw target character because you need them to stand face to face as you work on an animation.

This is a Blender script for rotating -/+180° and adding PositionOffset to a forward throw Target animation. This will be documented soon. | |||
