How do I create node base on the select material?

[joe-deng]

Hello guys,
I am thinking to write a very simple mel script which can create nodes and hook up with the multi material I select.
Here is what I stuck...

For example my shader call MAT_myShaderA, I want to have my nodes call this name with node's prefix
ex. remap_myShaderA, minus_myshaderA

here is my script so far...just can't get the name right.

string $sel_mat[] = (`ls -sl -type "lambert"`);

for($item in $sel_mat){
    shadingNode -asUtility plusMinusAverage -name "$sel_mat";
    shadingNode -asUtility remapColor-name "$sel_mat";
    }

next step will be hook them up!

Thanks for your help!

Ok even the name still an issue but I can move on...
here is my script for now:

string $sel_geo[] = (`ls -sl -type "geometry"`);
string $sel_mat[] = (`ls -sl -type "lambert"`);


shadingNode -asUtility plusMinusAverage -name "MINUS_111";
shadingNode -asUtility remapColor -name "Remap_111";

setAttr "MINUS_111.operation" 2;

connectAttr -f ( $sel_geo[0] + ".CTRL_transparency" ) MINUS_111.input1D[0];
connectAttr -f ( $sel_geo[0] + ".CTRL_transparency" ) MINUS_111.input1D[1];
setAttr MINUS_111.input1D[0] 1;


connectAttr -f MINUS_111.output1D Remap_111.colorR;
connectAttr -f MINUS_111.output1D Remap_111.colorG;
connectAttr -f MINUS_111.output1D Remap_111.colorB;

connectAttr -f Remap_111.color ( $sel_mat[0] + ".transparency" );

Nothing wrong when run this, but somehow it stop after the nodes created.
I need to have a "step2" script to connect them
here is the step2:

string $sel_geo[] = (`ls -sl -type "geometry"`);
string $sel_mat[] = (`ls -sl -type "lambert"`);


//shadingNode -asUtility plusMinusAverage -name "MINUS_111";
//shadingNode -asUtility remapColor -name "Remap_111";

setAttr "MINUS_111.operation" 2;

setAttr MINUS_111.input1D[0] 1;
connectAttr -f ( $sel_geo[0] + ".CTRL_transparency" ) MINUS_111.input1D[1];


connectAttr -f MINUS_111.output1D Remap_111.colorR;
connectAttr -f MINUS_111.output1D Remap_111.colorG;
connectAttr -f MINUS_111.output1D Remap_111.colorB;

connectAttr -f Remap_111.color ( $sel_mat[0] + ".transparency" );

Any idea why causing that?
Thanks!
