Edge Fusion is a post-processing effect for Universal Render Pipeline that blends edges between objects to eliminate hard seams and produce cohesive, natural-looking scenes. Add it as a Render Feature and control it through a Volume, with both global and per-object settings to target exactly where blending should occur.

🌟 Key features:

- Edge blending: smooths transitions between meshes, terrain, and props without changing materials or geometry.

- Global control via Volume: intensity, world‑space radius, max blend distance, and max screen radius.

- Intra-object fusion (optional): blends within the same mesh based on normal/depth discontinuities.

- Per-object overrides with Edge Fusion Object: custom radius (0 disables), include children with layer mask.

- Performance tuning: sample count, binary search steps, jitter (TAA-friendly), 3D noise (intensity/scale), shadow protection.

- Blend layers: choose precisely which objects participate in blending, including exclusion rules.

- Debug views: object IDs, Edges, Blending, Normals, and Depth.

- Compare mode: realtime side-by-side view to compare the original with the applied effect.

- Editor friendly: optional Scene View rendering; can run even if the camera’s post processing is off.

🎯 Ideal usecases:

Modular environments: hide seams between tiles, walls, floors, cliffs.
Terrain + props/materials: blend contacts for rocks, sand, snow, mud, gravel, dust, ice, ash, soil, moss, roots, asphalt/roads, ...
Kitbashing/mixed packs: unify assets from different styles and PBR setups.
Photogrammetry: soften scan boundaries when merging with terrain/meshes.
Foliage/debris contacts: reduce harsh intersections for more believable placement.
Intra‑object smoothing: reduce visible splits/normal seams on segmented meshes.
Cinematics/marketing: fast polish without editing materials or geometry.
Prototyping/blockouts: Instant cohesion while iterating layouts.

➡️ Getting started:

1) Add the Edge Fusion Render Feature to your URP Renderer.

2) Create a Global Volume (or use an existing one) and add “Kronnect/Edge Fusion”.

3) Adjust intensity and radius; set your blend layers.

4) Optionally add Edge Fusion Object to specific GameObjects for fine control.
