I use for a bit of time the standalone and I find the way is organised the render passes much more efficient and easy to understand (user friendly)
separate as Beauty passes/Post processing/render Layer/light passes. much easier to use and to understand.
for the maya I'm still trying to understand how is work lightpasses and after long hours of research I manage to use in the right way the render layer and all power and possibilities this feature gives.
Maybe if we could have for a next update the same way so we can use in the easy way. Please... if also some one know how to use light pass on "Maya" please would be awesome to show at the forum because at the manual???
I like the new plug for maya be able to use the Standalone 2.23.2 is really good

Thanks Guys
