# Cyberpunk: Broken Edges (GAT #85)

Author: Simon Schreibt. Captured 2026-10-16. Extends Fallout 3 – Edges.

## Observation
- Fallout decals add surface detail without changing silhouette.
- Cyberpunk 2077: Phantom Liberty breaks straight concrete wall silhouettes convincingly—looks like unique mesh, but is not.

## Technique
1. Simple beveled box wall.
2. Detailed mesh stuck into wall (overlap); 3 materials → 3 draw calls.
3. Intersection looks ugly; ordinary decal on top still shows seam.
4. Another decal layer with POM (height map) blends both geometries; sharp stone cracks + depth.

## Artifacts
- POM depth appears to change with distance / push downward in-game.
- Oskar Świerad (CDPR): step count depends on angle—artifact of that or interpolation.
- Comment: likely distance LOD of POM steps (larger steps, fewer counts).
- No tessellation; anisotropic filtering didn’t change the artifact.
