Handle pivot point script

I want to introduce handle helper scripts: HandleStart.py and HandleFinish.py.
Those scripts will help to create handle object with user defined pivot position.

How to use.

Content files:
handlestart.py
handlefinish.py
testscene.fbx

Simple video tutorial:

Annotations:
Create null object and rename it as “handle”. The position of these helper object will be used by new handle.
Then select objects, witch you want to transform together and run HandleStart.py. New handle with defined pivot position will be created.
To cleanup handle object, run HandleFinish.py script.

MotionBuilder Animation, FBIK, Python, Script

Geometry warning, bone is N degrees away from it’s roll axis

When you preparing your skeleton to export to MotionBuilder, You need to be sure that all your roll bones lies on their parent’s roll axis. What does it mean? To answer, look at the parent local axis direction. It must look at the roll bone’s child. It’s like you can create a line between parent and child bones of the roll bone and check if you roll bone lies on it. Roll bone just devide this line without any bends.

On the left – wrong roll bone position, on the right – good roll bone position

Another very important thing is to make it clear that your bones orientations are alined. Maya has very usefull command to do that – orient joints tool.
