After Effects 2026 draws Fractal Noise's Block noise at Scale 100 and Complexity 1 in cells of 66.67 px (the value changes every 66.67 px along a row), not 100 px; Soft Linear noise has the matching correlation length. EffectCraft's lattice is now Scale x 2/3 px (NOISE_CELL), CPU and GPU. Case 904 E03 (Soft Linear, Complexity 4, Scale 100): the noise's autocorrelation at 32 px was 0.68 (AE 0.41), now 0.54; pixel values cannot match (other seeds). Still open: AE's noise spreads about 20 % wider around its mean (std 48 vs 40/255 in E03). Existing projects and the Backgrounds presets with Fractal Noise get finer noise (two thirds of the former cell size). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
