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)	0.5
Density	`rows`	4..200	40

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": "blockShift", "params": { "amount": 0.5, "rows": 40 } }

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(){ float row = floor(vUv.y * uRows); float seed = rand(vec2(row, floor(uTime*2.0))); // Fraction of rows that ever shift now scales with amount — at max, // nearly every row is in play instead of a fixed ~30% ceiling. float thresh = 1.0 - clamp(uAmount, 0.0, 1.0) * 0.94; float shift = (seed-0.5) * uAmount * step(thresh, seed); gl_FragColor = texture2D(uTex, vec2(fract(vUv.x + shift), vUv.y)); }
