Quote - I see the work flow as:-

1. Use script to convert existing joints to weight maps. This just speeds up the process already available to Pro users in the Joint Editor. (If you are on the beta team I've now posted that to the RDNA beta forum.)

2. Starting from that base fine tune and enhance the weight mapping as required.

3. Create some form of injectable weight map pose that may then be redistributed.

 

So just clarify what the script does in noob terms... 

It automates the process of going through each axis of each joint and pressing the  'merge to weight map' button, but does not modify the results from what one would get if they actually went manually through each joint and axis and pressed the button?
