I'm trying to make a glass plane that zooms in whatever you see behind it, I tried this material from another question but it didn't work
I think what this is supposed to do is to scale all the light that comes through the Z Normals?

1$\begingroup$ For that to work (the IOR 0.0 trick) you need to have the surface normal pointing the correct way - the opposite way to that you would expect. The IOR of zero will effectively direct the incoming rays directly along the Normal - so it can be used to bend incoming (parallel) rays as if the surface acts lens.

- Model a magnifying glass lens (biconvex)
- Set its color to white
- Use raytrace transparency

$\begingroup$ Could you elaborate on what raytraced transparency is? $\endgroup$– LinguiniCommented Oct 14, 2018 at 20:05

$\begingroup$ It's transparency+refractions. See more -> docs.blender.org/manual/nb/dev/render/blender_render/materials/… $\endgroup$ Commented Oct 15, 2018 at 5:43
