[Maya-Python] Get the current render for each render layer

[Leonardo Bruni]

Hi guys, 
i'm tryng to get the renderer used by each renderLayer, there's something that i don't understand.
normally without renderLayers the command is simple:

cmds.getAttr('defaultRenderGlobals.currentRenderer')

My wrong logic said: "ok, just get each renderLayer and get the currentRenderer"

so:

import sys

import maya.cmds as cmds

import maya.mel as mel

render_layers = cmds.ls(type = 'renderLayer')

for rl in render_layers:

print cmds.getAttr('%s.currentRenderer' % rl)

But is not the way apparently...
So the question is: how i can get for each renderLayer the current render engine ?

Thanks in advance

Leo

Didn't test this out very thoroughly...but you can check all of the adjustments (layer overrides) for any layer using this (if you're using pymel):

pm.PyNode('layer1').listAdjustments()

then if you find an adjustment you like that's connected to the defaultRenderGlobals.currentRenderer:
adjustment.get()

That will give you what you're looking for I believe.

Oh and sorry, I forgot to point out that this is ONLY in the case that you've created layer overrides per render layer (which is what I figured you did since you'd just simply check defaultRenderGlobals.currentRenderer otherwise).
