Me: How do I show all the details?
Also me: It couldn't be that easy... 🔍

I'm quite surprised this approach was workable for this project. Realtime raytraced refraction in Unreal 4.27 to achieve this shot for Substance 3D.

It's raytraced thin translucency with refraction enabled. If the glass appears black then it's because your refraction rays are too low (post process volume). Ray traced translucent shadows are off because it causes a lot of noise when viewing objects through the lens and wasn't needed for this shot.

Hope that's useful - more tips for how I make these videos:

Mesh was shaped like a magnifying lens with a flat side toward the camera to prevent fish eye look. I think I may have enabled "output velocity" in the glass material settings to help the translucent sort properly with depth of field from the cinematic camera. Lens was attached to the camera (because it's tiny and easy to lose!) and then had it's own little animated transforms done in sequencer tracks.
