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)	0.6
Block Size	`scale`	0.005..0.08	0.025

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": "datamosh", "params": { "amount": 0.6, "scale": 0.025 } }

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(){ vec2 block = floor(vUv/uScale)*uScale; float n = rand(block + floor(uTime*4.0)*0.13); // How many blocks ever get touched now scales with amount too, not just // how far they move — at max, nearly every block is fair game instead of // a fixed ~45% no matter how hard the dial is pushed. float thresh = 1.0 - clamp(uAmount, 0.0, 1.0) * 0.92; vec2 off = (vec2(rand(block+1.7), rand(block+5.3))-0.5) * uAmount * 0.4 * step(thresh, n); gl_FragColor = texture2D(uTex, vUv + off); }
