I wanted to check my work, so I set up the EnvSphere with the famous Doge's Palace HDRI. This has buildings against a bright white sky.

This is with the blur set to .1. The reflections look sharp to me.

I don't use blur = 0 very often, because I like to use pretty crappy min shading rate for speed, and so you sometimes see jaggies in reflections. By softening reflections a bit, those jaggies go away. This saves me having to use costly low MSR for the whole scene.

A blur of .1 is not enough to smear reflections on a curved surface - but just enough to hide pixellation artifacts.

Now, being that we're up close here, the unnatural smoothness of the sclera is revealed. A closeup requires that you no use EyeSurface, but rather you set up cornea and sclera for the reflections. We'll get to that later.
