Display Layer Editor / get selected layers

[johan Borgström]

Hi,

I am trying to get the selected display layer.

I know you can get the display layers with:

pm.ls(type='displayLayer')

But that just returns a list of the available layers. As far as I could see there were no attribute on the returned layers to hold info whether they were "selected" or not. So I am guessing I need to get that info from the "layer editor itself".

Should be quite straightforward, but I havent found any good docs on how to do this, any tips?

Cheers, Johan

Hi Johan,

getLayerSelection "Display" is the MEL command you need

Hi,

I am trying to set layer visibility, tried both pymel and cmds:

import pymel.core as pm

layer = pm.PyNode('layer1')

layer.visibility.set(True)

print layer.visibility.get()

# True

import maya.cmds

cmds.setAttr('layer1.visibility', True)

print cmds.getAttr('layer1.visibility')

# True

The layer visibility is set but the display layer editor won´t reflect this. Is this a bug? Do I need to call an "refresh/update" on the editor or set the vis "through" the editor object somehow...

Regards, Johan

Hi Johan,

You need to use the layerButton command after setting the visibility of the layer:

layer = pm.PyNode('layer1')

layer.visibility.set(False)

layerVisibility =  layer.visibility.get()

# True

layerButton(layer, e = True, layerVisible = layerVisibility)

Hi Neil,

Thank you very much!

Hi again,

Regarding the "getLayerSelection" MEL script. I had a look at the proc found in: (C:/Program Files/Autodesk/Maya2019/scripts/startup/layerEditor.mel) and it seems like it loops through the layer editor and appends the selected layers to an array which is then returned. This means that we can not get the layers in the order they were selected. Can this be done someway? (Not super important but interesting to know)

BR,

Johan
