Start PIE.

Change the reflection method in postprocess volume to SSR

SSR reflections occur on the cube/sphere.

Approach the cube, the reflections remain consistent.

Set r.SSR.Stencil 1

As you approach the cube now, the reflections are bound to an "internal" texture inside a black environment on the cube. If you turn away, the texture is culled once you force it outside of the bounds of the cube. If you look away entirely the cube becomes+remains entirely black.
