How to Delete a Render Setup Layer Using Python?

[Anonymous]

Hello!

Anyone know how to delete a render layer in the new render setup using python? Right clicking on a layer and hitting delete works, but I have no idea what command it's firing to delete the layer and any associated collections/overrides. Deleting the layer node directly causes all the errors 😕

Thanks for your time and help!

I just know how to remove all render layers:

import maya.app.renderSetup.model.renderSetup as renderSetup

rs = renderSetup.instance()

rs.clearAll()

Same question, I can't delete an "specific" render layer (not all)  with python with render setup.

Wish there was a direct Python call to delete individual layers but this worked for me:

# get the renderSetup JSON data
data = renderSetup.instance().encode(None)

# get render layers
old_layers = data['renderSetup']['renderLayers']
 
# filter however you want to
new_layers = [x for x in old_layers if x['renderSetupLayer']['name'] != 'YOUR_LAYER_NAME']

# replace the render layers
data['renderSetup']['renderLayers'] = new_layers

# write the new render setup data
renderSetup.instance().decode(data, renderSetup.DECODE_AND_OVERWRITE, None) 

Also works with collections: 

for layer in data['renderSetup']['renderLayers']:
    if layer['renderSetupLayer']['name'] == 'YOUR_LAYER_NAME':
        old_collections = layer['renderSetupLayer']['collections']
        new_collections = [x for x in old_collections if x['collection']['name'] != 'YOUR_COLLECTION_NAME']
        layer['renderSetupLayer']['collections'] = new_collections

Scratch my previous reply, found a way with just a couple direct calls:

import maya.app.renderSetup.model.renderLayer as renderLayer
import maya.app.renderSetup.model.renderSetup as renderSetup

rs = renderSetup.instance()
layer = rs.getRenderLayer('YOUR_LAYER_NAME')
renderLayer.delete(layer)

just in case someone wants to delete collections:

import maya.app.renderSetup.model.renderSetup as renderSetup 
import maya.app.renderSetup.model.collection as collTool

layer = 'your_layer'
collName = 'your_collection' (can be just a part of the name)

render_setup = renderSetup.instance()
render_layer = render_setup.getRenderLayer(layer) 

collections = render_layer.getCollections()
if collections:
    for coll  in collections:
        if collName in coll.name():
            collTool.delete(coll) 
            print 'deleted ', collName,'from',layer
