I am trying to make a fresnel kind of effect that only is visible on the edges of an object. Kind of like a fading outline. So I tried to take the angle between the camera normal and object normal and depending on the size of the angle I want another color. This is how my shader graph looks like
I'm not sure if the vectors are normalized, hence the normalization nodes. Also not sure if the vector transformations from different spaces are correct, but I think so. The result looks like something I'm trying to achieve, but it's not so easy to see. Is there a way to visualize it better or "debug" the shader? And is this a correct setup for what I am trying to achieve?
