I built a post-processing transition pass that uses a noise-driven mask instead of a standard fade or wipe. The effect works by blending between two textures using a procedural-looking noise field, so the transition feels broken up, organic, and slightly glitchy rather than uniform. The mask is mirrored/tiled to avoid visible seams, and the transition edge is softened with an SDF-based shape so it has a controlled falloff instead of hard cutoff artifacts.
On top of that, the pass includes RGB channel separation and subtle vertical distortion, which makes the edge of the transition feel more alive. The amount of distortion changes with the transition progress, and the edge can be pushed further with per-channel offsets so the mask has a stronger chromatic split during the reveal. The result is a stylized noise-mask transition that works as a post-process effect over the full frame, rather than being tied to a single material.
Scroll down unitl you get to the mask section to see it!
