What it reads

Frame-local Reads only the current frame, which makes it the cheapest kind to stack and safe to render into a Conjure window at any size.

Parameters

param	key	range	default
Amount	`amount`	0..1 (rendered to 2)	0.55
Warmth	`warmth`	0..1	0.5

The renderer widens amount past its declared maximum by 2× before it reaches the shader, because most shader bodies were tuned against a muted top end. The rendered figure is the bound that actually arrives.

Defaults as a layer

{ "effectId": "lightLeak", "params": { "amount": 0.55, "warmth": 0.5 } }

GLSL fragment shader

The effect's own code. The uniforms and helpers above it — uTex, uFeedback, the depth proxy, the frame ring, depthAt(), timeAt() — are the same header every Ether-MOSH shader opens with, and are documented once on the registry rather than reprinted on all 143 pages.

void main(){ vec4 c = texture2D(uTex, vUv); float d = distance(vUv, vec2(0.1 + sin(uTime*0.3)*0.1, 0.5)); // Warmth runs the leak from a cold flare to a sun-struck orange one. vec3 tint = mix(vec3(0.35, 0.75, 1.0), vec3(1.0, 0.45, 0.15), uWarmth); gl_FragColor = vec4(c.rgb + tint * smoothstep(mix(0.35, 0.95, uWarmth), 0.0, d) * uAmount * 1.5, c.a); }
