Maya blendshape (MEL question)...

[Anonymous]

Hello, I am new to mel scripting, so please bear with me. I am trying to transfer my blendshapes from my Daz3d rig to my custom one.
I am duplicating them one by one, but I have multiple characters, so I am trying to make a script to do it for me.

so far this is what I got:

select -r -sym GenesisFBXASC046Shape ;
setAttr "GenesisFBXASC046V4_PHMEyeOpenFBXASC045CloseR_head.Genesis_V4_PHMEyeOpen_CloseR_head" 1;
duplicate -rr;
// Result: GenesisFBXASC046Shape1 //
setAttr "GenesisFBXASC046V4_PHMEyeOpenFBXASC045CloseR_head.Genesis_V4_PHMEyeOpen_CloseR_head" 0;

I have 50 blendshapes so far for each character, what would be the best course of action for this scripted?

Thank you for your time.

If you want to make the script work for all blendShape then you can use the following MEL procedure. It is a generic procedure.

proc blendShapeSetAttribute(int $blendShapeCount, string $shapeName, string $attrName)

{

    string $shape = $shapeName;

    string $attr = $shapeName + $attrName;

    for ($count=1; $count<$blendShapeCount; $count++)

    {

            if ($count != 0)

            {

                $shape = $shapeName + $count;

                $attr  = $shape + "."+ $attrName;

            }

          select -r -sym $shape;

          setAttr $attr 1;

          duplicate -rr;

          setAttr $attr 0;

    }  

};

The above procedure will work for any blendShape or any polygons.  I have executed the above procedure like below for “pSphere”.

blendShapeSetAttribute(50, "pSphere", "scaleX");

for “pSphere1” to “pSphere49” it will select the current sphere and set the given attribute “scaleX” to 1.

In your case, if attribute name is same irrespective of shape count and shapeName starts with 0 instead of 1, then use the below procedure.

proc blendShapeSetAttribute(int $blendShapeCount, string $shapeName, string $attrName)

{

    string $shape = $shapeName;

    for ($count=0; $count<$blendShapeCount; $count++)

    {

            if ($count != 0)

            {

                $shape = $shapeName + $count;

            }

          select -r -sym $shape;

          setAttr $attr 1;

          duplicate -rr;

          setAttr $attr 0;

    }  

};

Call the procedure like below.

blendShapeSetAttribute(50, "GenesisFBXASC046Shape", "GenesisFBXASC046V4_PHMEyeOpenFBXASC045CloseR_head.Genesis_V4_PHMEyeOpen_CloseR_head");
