    Hey everybody!

    Can anyone tell me how to convert a WorldNormalVector to a normal in screen space?

    I've been googling for the past hour with no results... :(

    Thanks!

    How did you end up with world-space normals in screen-space? Is this something Unity's built-in Deferred path does?

    Not sure if you want cam/eye/view-space since "screen space" is 2-dimensional ;) is this in a post-processing shader or in a surface shader?

    I didn't :p That's that I need.

    Camera or screen space would do (I'm only interested in the .xy anyway), it's a surface shader. So what I think I need is a _World2Camera matrix, which doesn't seem to exist, sadly;.
