Expression Issue

Posted in: Maya
I put this bit of code together and I’m stuck as to how I can integrate the simple expression below into one that uses the string names of the lights. As you see it’s just a basic formula telling the rim light to be the key * 2/3.

——-UPDATE——–

Nevermind. I figured it out!

Code:

global proc js_lightSetup ()
{
        spotLight;
 rename "keyLight";
 string $keyLight;
 string $kl[]= `ls-sl`;

        for ($key in $kl)
          {
                setAttr ($key+".scaleX") 6.0;
                setAttr ($key+".scaleY") 6.0;
                setAttr ($key+".scaleZ") 6.0;
          setAttr ($keyLight+".intensity") 1.0;
         
    move -r -ls -wd -42.0 102.7 86.0;
 rotate -r -os -46.0 -26.0 0;           
 xform -ws -rp 0 0 0 -sp 0 0 0; 
  }
 select -r $kl; 
 int $size= size ($kl);
   
//create fill light             
             
 spotLight;
 rename "fillLight";
 string $fillLight;
        string $fl[] = `ls -sl`;

        for ($fill in $fl)
          {
                setAttr ($fill+".scaleX") 6.0;
                setAttr ($fill+".scaleY") 6.0;
                setAttr ($fill+".scaleZ") 6.0;
 setAttr ($fillLight+".intensity") .5;

  move -r -ls -wd 37.6 80.6 102.0;
 rotate -r -os -31.0 25.0 10.0;               
 xform -ws -rp 0 0 0 -sp 0 0 0; 
  }             

 select -r $fl;
 int $size= size ($fl);
   
//create rim light
           
 spotLight;
 rename "rimLight";
 string $rimLight;
        string $rl[] = `ls -sl`;

        for ($rim in $rl)
          {
                setAttr ($rim+".scaleX") 6.0;
                setAttr ($rim+".scaleY") 6.0;
                setAttr ($rim+".scaleZ") 6.0;

              // expression -s "rimLightShape.intensity=rimLightShape.intensity= keylightShape.intensity * 2/3;";
  // expression -s "$rl.intensity=$rl.intensity= $kl.intensity * 2/3;"

 move -r -ls -wd 0 76.5 -104.0;
 rotate -r -os -142.0 -1.0 0; 
                xform -ws -rp 0 0 0 -sp 0 0 0; 
      }

 select -r $rl;
 int $size= size ($rl);
}
