PolySmooth on SkinCluster

I try to find a way to copy "the Skinweight of my poly with a smooth poly on it" on "the same poly but with his smooth poly directly applied" .
So I delete the history on my copy, so I have my high poly I skin it with smooth bind and now i want to copy the Skincluster of my original Poly on his copy but apparenlty maya never copy the skincluster in considering the smooth poly.

I have tried :
Export Skin Weight
Copy Skin Weight
and multiply script :
copySkinCluster.mel
fixWeight.mel
xyHistoryTools.mel
saveWeights.mel

None give the good result.

So Anyone know a mel script who can do this ?

Thanks.

When you do a smoothPoly Maya doesn't know what to do with the extra points that are created. Those points didn't exist when the skinCluster was created.

I suppose using wieght maps might work, but you say you haven't had any luck with that.

I don't understand why you need a whole new peice of geometry to be bound. You can just smooth the low poly version and keep your wieghting. Since the high poly (smoothed) geo is derived from the bound low poly geo it should react fine.

Hope this helps.

Well James I want to export my poly in direct X file and the exporter for maya doesn't support a Polysmooth on Skincluster.
