Expressions - How to set attributes using string variables?

[dkrelina]

Hi,

I'm trying to create an expression that sets the color of multiple materials using a loop. I would like to store the name of all the materials as an array of strings. How do I use a string variable to set an attribute, rather than hard-coding it?

For example...

$mat = 'lambert2';

lambert2.colorR = 0;      // This works
$mat.colorR = 0;          // This doesn't... How do I get it to work? How do I set an attribute?

Hi!

$mat + ".colorR"

Thanks @mspeer. After doing a bit more research, this is what I was looking for...

$mat = "lambert2";
setAttr ($mat + ".colorR") 0;
