Copying Vertex Alpha Channel Into Rgb Channels

[rgkovach]

I'm trying to convert a Vertex Color Set's Alpha data into RGB color data...
I figured this would be easy to do in MEL, but my script is failing, i think, because of the large number of vertices (the script terminates at the 739 vert, the mesh has 11000 vertices).

here is my script:

CODE
$verts=ls -sl -flatten;
int $i=0;
for ($i=0; $i<size($verts); $i++)
{
    //select -r $verts[$i];
    $alpha=polyColorPerVertex -q -a $verts[$i];
    //print ("Alpha = " + $alpha[0] + "\n");
    $roundedValue=roundoff $alpha[0] 3;
    //print ($roundedValue + "\n");
    polyColorPerVertex -rgb $roundedValue $roundedValue $roundedValue $verts[$i];
    polyColorPerVertex -a 1 $verts[$i];
    print ($i + " of " + size($verts) + "\n");
}
print "done...\n";

Also, i've been trying to export vertex color data using the Export Attributes Maps within the Paint Vertex Color tool, but the resulting map has a faceted look instead of a smooth look...the Maya docs are painfully vague on the topic of exporting attribute maps, so any help or tips greatly appreciated...

thanks.

in general loops like this is outsideof mels scope.But try to actually ask the wjhole set in one comand instea dof querrying it sindie a massive loop. (because unknown to you its a loop of loops)

[rgkovach]

when you say, query the set in one command, do you mean outside of MEL through the API?
or do you mean i should write a MEL script that gets all the data first?
thanks

no getAttr can querry the whole array.
