This is a fullscreen Sobel (outline) shader that I implemented in T3D, using a this resource.

Is it possible to do this in Unity?

I wouldn't know but i love that style, borderlands did it but tbh i think they went over board.

Yeah, I like the effect that scattersky gives with the outline shader.

Fullscreen and Per Material Shaders are both possible in Unity.

Gotta get pro though.

For full screen shaders you must have unity pro, but you can get materials for the objects that have the outline.. It's part of the cartoon shader or something
