Kill the hard seams between objects, no material edits, no geometry changes. Edge Fusion is a URP post-processing effect that softly blends the boundaries where meshes, terrain and props meet, turning kitbashed and modular scenes into cohesive, natural-looking environments.
Add it as a Render Feature, control it through a Volume, and target exactly where blending should happen with both global and per-object settings.
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 for:
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.
