Understanding shading groups

Maya collects all of the objects that share a single material into something…called a Shading Group and you just need to understand what that is.…So let's open up the Hypershade and take a look at it,…Window>Rendering Editors>Hypershade.…Now the apple_blinn material here is currently assigned to both of the apples.…If I select that and then graph its network by right-clicking and choosing…Graph Network, you'll see all the shading notes including once again the…texture placement, the fractal noise and some other cool stuff you'll learn about…later in the course.…

But these are all the material shading nodes that go into this shader network …or composed at shader tree.…But when we graph the network in that way, we don't see the Shading Group.…And to see that Shading Group what I can do is I can click on the material here…in the tab and then click on Input and output connections on the Hypershade…toolbar, click on that.…And it graphs the same network, except this time we see something that says blinn2SG.…
