Transfer envelope weights

["Bernard Lebel" <3dbernard(at)gmail.com>]

Hello,

Anyone has experience with transferring envelope weights? I'm talking
about saving out weights to file, and re-apply those on the same mesh
later on.

Here are my results:

After:

I have a run a script that prints the weight values before and after,
and the differences are very minor (rounding errors after the fifth
decimal for 10% of the total values, which I think should be quite
acceptable).

I have tried both by writing weights to an XML file and to save a preset.
All envelope operators were frozen.
The weights were written when the character is in neutral pose, and
reapplied in the same fashion.
The construction is set to Animation when the weights are imported.


One thing: if the character already has an envelope correctly set,
then the ugly deformation does not occurs.


Thanks
Bernard
