If you are like me (unable to keep the Attribute Spread Sheet open or navigating through all the paremeters drives you crazy) this is the GUI for you!
Manage all the render attributes (like "primary visibility" or "visible in reflections") on the selected objects from a single GUI.
And if you start to find random orange attributes (layer overrides) you can clean them from the current layer with just one click.
Happy overriding!

# HOW TO INSTALL:
Put the renderAttrEditor.py file in your Maya script folder.
ex: c:\User\YOUR_USER_NAME\Documents\maya\scripts

# HOW TO USE:
Open the script editor and, in a python tab, write:

import renderAttrEditor
renderAttrEditor.renderAttrEditorUI()

You can save the code to a button by selecting and dragging it to a shelf.
