Display vertex color in the viewport using MEL

[ivan.antonovRTYBF]

Hi there.

Probably I am looking for something evident for technical artists.
But I can't figure out how to switch vertex color in the viewport using mel.

I tried to use the command I found in the ColorSet Editor.
colorSetDisplay 1"-colorShadedDisplay" 1;
But it causes the following assertions.
// Error: line 1: Cannot find procedure "colorSetDisplay". //

Probably the problem is the ColorSet Editor has to be run somehow before calling a command placed in it. But I have no idea how to do that.

I would appreciate any help or explanation.
Thank you.

Hi!

vertexColor isn't a viewport attribute, it's a per object attribute that can be turned on by setting the "displayColors" attriubte on a mesh shapenod to 1.

This Mel command will turn this command on for all meshes in the scene:

proc switchOnColorDisplay(){
    string $geo[] = `ls -type "mesh"`;
    for ($g in $geo){
        setAttr ($g + ".displayColors") 1;
    }
}
switchOnColorDisplay()

This will turn it off for all the meshes in the scene:

proc switchOffColorDisplay(){
    string $geo[] = `ls -type "mesh"`;
    for ($g in $geo){
        setAttr ($g + ".displayColors") 0;
    }
}
switchOffColorDisplay()

I hope it helps!
