MossgateRuins

• Render pipeline: URP only. Tested in clean projects (import, render, Play Mode): Unity 6000.4.3f1 + URP 17.4.0 and Unity 2022.3.62f3 LTS + URP 14.0.12. Built-in RP and HDRP are not supported.
• Unique models: 33. Prefabs: 33.
• Triangles: 10–370 per model; 4,360 for one of each model.
• Example scenes: Forest Ruin 16,045 triangles; Sunken Vault 9,592 triangles; one material in both.
• Materials: 1 (URP/Lit, albedo + emission).
• Textures: 1 albedo atlas + 1 emission map, 1024 × 512 PNG, point filtering (pixel-art style), 16 texels per metre.
• UV mapping: yes, single shared atlas, no overlapping UVs. Lightmap UVs are generated on import for static pieces.
• LODs: no.
• Rigging: no. Animation: no animation clips. Door, chest lid and lever move through a C# hinge script (MossgateHinge: Open / Close / Toggle, UnityEvents).
• Scripts: 3 (MossgateHinge, MossgateLightPulse, MossgateDemoCycler for the demo scenes only).
• Colliders: box, capsule or exact mesh colliders per piece; doorway and gate openings are free; movers use kinematic Rigidbodies.
• Static flags: set per use; movers are not static; small scatter does not contribute to GI.
• Scale: real-world metres (2 m grid, 3 m walls). Pivots: cell centre for floor pieces, edge middle for walls, grid vertex for pillars.
• Scenes: 4 (Catalog, Forest Ruin, Sunken Vault, Mechanisms).
• Source: editable Blockbench .bbmodel included.
• Not measured: FPS, memory and mobile performance. Light baking was not tested.

Build overgrown courtyards, sunken stairwells, underground passages and small treasure vaults from one modular kit.

Mossgate Ruins is the weathered limestone home of a forgotten order of wayglass keepers, now reclaimed by moss, roots and ivy. Every arch keystone holds a glowing turquoise wayglass crystal, every pillar carries the same carved seed-spiral, and the joints of the flagstones are filled with moss.

Modular by design

• 2 m grid with clear rules: 3 m walls, pillars on grid vertices that close every corner, T and X junction, 1 m height steps.
• Arched doorway (1.125 × 2.25 m clear opening) and a 4 m arch gate; their colliders never block the opening.
• Stairs and stackable platforms meet flush, so terraces and stairwells going up or down need no manual scaling.
• Separate ceiling pieces for underground rooms; group them and disable them for top-down cameras.
• Joints were checked in the example scenes: 2,301 touching piece pairs, 0 visible z-fighting overlaps.

Content (33 models, 33 prefabs)

• Structure: floor, broken floor, grass ground, platform, stairs, ceiling, broken ceiling, wall, low wall, collapsed wall, arched doorway, barred window, pillar, broken pillar, arch gate
• Ruin detail: rubble pile, fallen column, stone debris
• Nature: ivy drape, root tangle, old tree, shrub, grass tuft, wild flowers
• Decor: wayglass brazier and wall sconce (with point lights), hooded keeper statue, seal altar, urns, gold pile
• Mechanisms: door, treasure chest and floor lever, driven by one small script with UnityEvents (the lever can open the door)

Included scenes

• Catalog of all prefabs
• Forest Ruin: walled courtyard with terrace, gate and forest
• Sunken Vault: ruin entrance, 3 m stairwell, corridor and treasure vault behind a lever-operated door
• Mechanisms: door, chest and lever demo

Fast and simple to use

• One shared URP/Lit material and one 1024 × 512 atlas (+ emission map) for the whole pack.
• 10–370 triangles per model; colliders and Static flags set up for real use.
• Editable Blockbench source file included.
