Scene Color node completely gray

Unity Engine

I’m new to shaders and lighting and whatnot, but no matter what I try, it seems like the output of the Scene Color node is always flat gray.

I’m using the default LWRP settings, the default Sample Scene, and a plane above the entire thing that I’m trying to use a shader to make transparent (to eventually add cooler effects). To this end, I created PBR Graph with Scene Color going directly into the Albedo. As I understand it, that should make the plane completely transparent, regardless of other settings. Is this wrong, or is there actually something weird going on?

Edit: Okay, I figured that out, I had to set the PBR Master Node Surface type to Transparent, and use the Screen Position Node’s output as the UV for Scene Color. But now I have another weird problem that should probably be its own post.

Found this post here from AxonGenesis that fixed it for me: http://answers.unity.com/answers/1717054/view.html

You also need to enable the “Opaque Texture” feature on your camera and ideally on the Render Pipeline asset as well.
