Description

Refractive Lens

A convex glass dome that actually refracts — the image inside sits behind the surface and slides around as you move the camera, like looking into a real cornea or a cut gem. Procedural iris out of the box, or drop your own texture in and it parallaxes too.

The trick is one clean Snell refraction. The material treats the visible surface as a little convex cap over an inner plane: it bends the view direction through the dome against the surface normal, then projects that bent ray straight down onto the surface to get a UV offset. Slide the inner image by that offset and your eye reads it as depth — the thing inside genuinely shifts as the camera orbits, instead of being painted flat on the surface. IOR sets how hard the dome bends (1.0 is dead flat, glass lives around 1.45, crank it past 2 for a gemstone), and Lens Depth sets how deep the cavity feels. The inner image is built procedurally in a tiny HLSL block — radial iris fibres, a ring of facet wedges, a dark pupil in the middle — so it works with zero textures, and a Tint rides over the top for the colour. There's a Fresnel rim on the edge for that wet, glassy sheen, and the whole cap fades out at its silhouette through a soft circular mask so it reads as a rounded lens, not a flat disc. No animated noise anywhere, so it's rock-steady under TSR.

Settings you have to set

None of these come across in the paste, so set them by hand or it won't look right. Pick one blend path:

  • Material Domain → Surface, Shading Model → Default Lit (both paths)
  • Glassy cornea / cap: Blend Mode → Translucent, Translucency Lighting Mode → Surface TranslucencyVolume, Refraction Method → None (the lens does its own UV refraction — you don't want the engine's on top), and wire the Opacity frame.
  • Solid gem / cabochon: Blend Mode → Opaque and just leave the Opacity frame unwired. Everything else is the same.
  • Wire each result node into its matching Material pin — they're parked next to the Material node in frames labelled Base Color, Emissive Color, Roughness, Specular, and Opacity. Root links never survive a paste.
  • Two Sided → Off for a normal convex cap.

Params:

  • IOR — how strongly the dome bends the view. 1.0 = flat (no parallax), 1.45 = glass/cornea, 2+ = gemstone. The headline dial.
  • Lens Depth — how far behind the surface the inner image feels. 0 = glued to the surface, hig
