I can't find more time at the moment than a simple copy/past of the symetrize command with a loop on points. A true "normalized weight" function doesn't look to complicate, I will try to write something soon if nothing is already available on the web ( I think a script already exist but I'm not sure...).

Cheers

Hey Guillaume,

 

Thanks for the script, unfortunately my character is a bit wierd and as such is asymetrical, I did try running it on an old character and got this error:

 

Disabling a souce operator is denied

 

But it does seem to have helped so...Thanks again,

Of course it is only a workaround for symmetrical object...

A quick and dirty script.
Select your object and run ! It symmetrize the weight from x positive side. As this command normalize the weights it then re symmetrize from the x negative side.
Tell me if it works for you.

var oPenguin = Selection.item(0);
var osymTemplate = CreateSymmetryMappingTemplate(oPenguin, true, 0, true);

var oGeometry = oPenguin.activeprimitive.geometry;
var oPoints = oGeometry.Points;

var oHalfPointsPlus = new Array();
var oIncr = 0
oEnum = new Enumerator( oPoints ) ;
for (;!oEnum.atEnd();oEnum.moveNext() )
{
    var oPos = oEnum.item ().position;
    if(oPos.x >= 0)
    {
        oHalfPointsPlus[oIncr] = oEnum.item().index;
        oIncr = oIncr+1;
    }
}
SymEnvWeight(null, oPenguin+".pnt["+oHalfPointsPlus.toString()+"]", osymTemplate, 0);

var oHalfPointsMinus = new Array();
var oIncr = 0
oEnum = new Enumerator( oPoints ) ;
for (;!oEnum.atEnd();oEnum.moveNext() )
{
    var oPos = oEnum.item().position;
    if(oPos.x <= 0)
    {
        oHalfPointsMinus[oIncr] = oEnum.item().index;
        oIncr = oIncr+1;
    }
}
SymEnvWeight(null, oPenguin+".pnt["+oHalfPointsMinus.toString()+"]", osymTemplate, 0);

Hey gang,

 

this is something that has been bothering me for a while now, how can I fix points that don't have a combined envelope weight of 100 %? I ran the script that Homam Bahnassi wrote for checking weights (cool tool)... problem is that it ends up tagging almost all the points on my charaters head. Now usually I would forge ahead and fix the weighting by hand, but this must be a comon problem so I thought I'd ask if anyone out there had a trick ( read script) up their sleeve for dealing with this annoying problem?
