Emissive Fresnel rim glow with pulse

Make the silhouette of a mesh glow with an emissive rim whose width follows a Fresnel power curve, independent of scene lights, with an optional slow pulse. Use for pickups, energy objects and highlighted interactables.

How it works

Shader type
spatial
Parameters
base_color (vec4 = 0.08, 0.1, 0.16, 1), roughness (float = 0.35), metallic (float = 0.2), glow_color (vec4 = 0.2, 0.85, 1, 1), glow_power (float = 2.5), glow_intensity (float = 3), inner_glow (float = 0.08), pulse_speed (float = 2) and 1 more
Result
A dark surface with a bright coloured edge that breathes slowly.

Limits to consider

An empirical Fresnel-style curve, not a physical Fresnel term. Flat faces seen head-on get no rim, so boxes glow only at grazing angles. Without the Glow post effect the emission does not bloom past the silhouette.
