Description

Iridescent Thin-Film

The real physical soap-bubble rainbow — a thin interference film whose colour genuinely shifts as you orbit the camera, drifting and banding across the surface like oil on water. Soap bubbles, oil slicks, anodised titanium, beetle shells, pearlescent paint — all from one Substrate master. Procedural out of the box, zero textures, no Custom HLSL — paste it, wire one pin, done.
This is built on Substrate's Thin Film node, which is the honest version of this effect: it simulates light actually interfering inside a microscopically thin coat and re-colours the surface's reflectance from that, so the hue sweeps with view angle the way real interference does. That's the difference from a car-paint-style fake, which just lerps a colour by Fresnel — here the rainbow is physics, driven by the film's Film Thickness and Film IOR. To stop it reading as one flat tint, a world-space Noise node varies the film thickness across the surface, so the colours pool and band and drift exactly like a soap film thinning toward its rim. The surface the film sits on is metalness-aware: leave Metalness at 0 for a grey dielectric base (soap, oil) where the look is pure interference, or push it up and set a Base Colour for coloured-metal iridescence (a green beetle carapace, anodised blue), where that colour becomes the metal's reflectance and the diffuse drops to black the physical way. It does both translucent and opaque — feed the optional Transmittance path and it's a see-through bubble wall; skip it and it's a solid shell. No Time anywhere, so it's TSR-safe.
Settings you have to set

Root-pin links never survive a T3D paste, so the output wiring is on you — the one result node sits next to the Material node in a frame labelled with its exact pin.
Substrate must be enabled (required): Project Settings → Engine → Rendering → Substrate → Substrate Materials = On. This is the default in new UE5.7 projects; if you just turned it on, restart the editor. Set Substrate GBuffer Format = Adaptive too, or the Haziness secondary lobe silently drops.
Wire the one labelled frame: the Substrate Slab BSDF node feeds Front Material (the purple pin). That's the only manual hookup.
For the see-through bubble / oil-film look: Blend Mode = Translucent Colored Transmittance, Two Sided = On, and on the Substrate Slab node set Sub Surface Type = Simple Volume (the paste bakes this as `MSS_SimpleV
