Symmetrical weight map

[SebasProulx]

I have a symmetrical mesh (it's a face). On that mesh , I have a weight map that is not symmetrical.

Anyone knows a way to copy the weight map from one side of the face to the other side? (script or anything)

I know the weight map could have been painted in Symmetry mode, but lets say it's too late now.

Thanks.

Edit: I assume you're talking about the weight map property and not the envelope weighs!

Hmm I use to have a nice script for that but can't find it atm, but heres a quick and dirty one that will do the job.
Make sure to have a Symmetry Map (has to have default name) on your model before running the script.
You can select a weight map map and it will create a symmetrical one for you or you can select 2 weight maps and it will symetrize the first selection into the second one.


wm = Selection (0);
obj = wm.Parent3DObject;
sm = obj.ActivePrimitive.Geometry.Clusters ("SymmetryMapCls").Properties ("Symmetry_Map");

if (Selection.Count == 2) {
wmNew = Selection (1);
} else {
wmNew = CreateWeightMap ("WeightMap", obj.FullName) (0);
}

wmArray = wm.Elements.Array.toArray ();
smArray = sm.Elements.Array.toArray ();
wmArrayNew = new Array ();

for (i = 0; i < wmArray.length; i ++) {
wmArrayNew.push (wmArray [sm.Elements.ItemsByIndex ([i]).toArray ()]);
}
wmNew.Elements.Array = wmArrayNew;


Cheers!

Thank you, it works well.

I would prefer something that would edit my actual weight map and symmetrize only on the selected points, but for what I needed to do right now, I was very helpful.

There's also LaMaison's WeightMapTools:

The "expression map" can be used to invert a weightmap, which depending on the ocassion, is sort of like symmetrizing it.

My mate Phil Barrenger's script may be the one you are referring to Serguei?

instructions for use are included in the script file itself.

wery wery handy :)

Nah I was referring to a script I wrote a while back! Found it since though :).
