Hello world,

I am, as always, fully incompatible with the Maya Help system. All I'd like to do is to set the visibility (or other attributes) of a layer to 1 or 0. Watching the Script Editor tells me that I can do a "toggle" all right, and even " layerSetTo Selected".visibility" "to a value, but I cannot find any hint on this in the help files.

I've tried "layerSetTo "mylayername.visibility" 1;" and others, but none work. I can't find help in the help files. All other threads that might have answered this are closed down with no conclusive answer or point to dead links.

Thanks world

Just use the setAttr command -

setAttr layer1.visibility 1;

Thanks a lot. Of course, the setAttr command...

As always I just figured it out myself about 5 minutes before my mailbox rang.

What you do when you wonder how things like that work:

step1: Turn on echo all commands in the scriptEditor.
step2: Do the action (click the V for a layer) to see what the scriptEditor prints out.
step3: Copy the proc (in this case "layerEditorLayerButtonVisibilityChange")...Long proc :) and copy it from the history field to your scriptField. Then add "whatIs" in front (without quotes)

whatIs layerEditorLayerButtonVisibilityChange;

step4:Maya prints:

// Result: Mel procedure found in: C:/Program Files/Alias/Maya7.0/scripts/startup/layerEditor.mel //


step5: Open the layerEditor.mel file and search for the proc. Then you find this:

global proc layerEditorLayerButtonVisibilityChange(string $layer)
//
// Description:
// This procedure is called whenever the user presses the visibility
// indicator in a display layer button.
//
// Toggle the visibility of the layer.
//
// Arguments:
// $layer - The layer.
//
{
int $visible = `getAttr ($layer + ".visibility")`;

if (0 == $visible) $visible = true;
else $visible = false;

setAttr ($layer + ".visibility") $visible;
}


Here you can easily see that if you extract the bottom line there, you just scored a goal in the world of mel;)
