Get material count of a given mesh in Maya 2012?

bpears

Hello. Is there a way to find all materials used within a single mesh ? I want to be sure I do not have extra materials from other parts mixed around and whatnot.

You can use this short script to report the number and names of materials assigned to your object, just select your object and enter this into the MEL command line at the bottom of the window (or turn it into a shelf button if you'd like):

{
    string $select[] = `ls -sl`;
    string $assigned[];

    for ($e=0; $e<`size $select`; ++$e) {
        string $shapes[] = `listRelatives -children -f -shapes $select[$e]`;
        string $SE[] = `listConnections -type shadingEngine $shapes[0]`;
        $SE = stringArrayRemoveDuplicates($SE);
        for ($i=0; $i<`size $SE`; ++$i) {
            string $surfaceShader[] = `listConnections ($SE[$i] + ".surfaceShader")`;
            if ($surfaceShader[0] == "" && `objExists ($SE[$i] + ".miMaterialShader")`) { 
                $surfaceShader = `listConnections ($SE[$i] + ".miMaterialShader")`; 
            }
            if ($surfaceShader[0] != "") { $assigned = stringArrayCatenate($assigned, $surfaceShader); }
        }
    }
    print (`size($assigned)` + " Materials:  " + (stringArrayToString($assigned, " - ")));
}
