Bernard,

It seems to me like an old bug of two deformers at exactly the same position (coordinates). But I doubt this is the problem if your saving to a file and bringing it back.

If not, do you script inputs and outputs the XML according to deformer names or index? Maybe the index is not the same?

If not is it possible that your reset pose is not that "reset" because you enveloped something else on these deformers into an other "reset" pose?

Hope it helps,

Thanks François.

I'm out of ideas. I have tried freezing the autoenvassign operator,
not freezing anything, chaning the number of deformers in the
autoenvassign, dumping the array values in the envelopop operator
.Weight property, in the cluster property .Elements property, both
together, nothing will work.

*sigh*

My wild guess would be something with the Automatic Envelope Assignment
operators. These are often forgotten and can screw the weights big time.
Freezing them solved many problems for me.
