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
Mix	`amount`	0..1 (rendered to 2)	0.85
Levels	`levels`	2..8	4

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": "paletteDither", "params": { "amount": 0.85, "levels": 4 } }

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); vec2 p = mod(floor(vUv*uResolution), 4.0); float bayer = (p.x + p.y*4.0)/16.0 - 0.5; vec3 d = c.rgb + bayer*0.15; d = floor(d*uLevels)/uLevels; gl_FragColor = vec4(mix(c.rgb, d, uAmount), c.a); }
