Possible to get Fresnel to work with ortho?

Is it possible to get a working Fresnel based material with an orthographic camera? All my attempts appear to be failures, but if it were possible I would be so happy.

never tried it, so cant answer that.
maybe a dot product is easier to work with?

Found a solution here! CameraVector DotProduct - Rendering - Unreal Engine Forums

Instead of Camera Vector set a vector that matches your camera’s direction ie. 0,0,1

Hello, I made a general solution to ortho Fresnel. Just posting here in case anyone else need a detailed version of the solution.

Here’s a screen shot of the effect. The code snippet is also provided.
