Stylized Modular Keep & Stronghold Kit

Build castles, keeps, forts, gatehouses and dungeon strongholds in minutes — and drop them straight into your engine.

Stylized Modular Keep & Stronghold Kit is a 20-piece modular set built around a strict 2 m grid. Walls land on grid lines, corners fill the gaps exactly, and pivots are placed so rotation and snapping just work. Assemble a 6 × 6 m crenellated courtyard out of the box: portcullis gate, gothic archway with door, barred window, parapet walkways, external stair and interior props.

A fully assembled demo keep and a lit night-corridor diorama are included as ready-to-open .blend scenes.

Everything you need to ship it

• PBR textures - 4 tileable sets (stone, wood, iron, cloth) with BaseColor,
    Normal and packed ORM (AO / Roughness / Metallic). Seamless, and the   generator scripts are included so you can re-bake at any resolution.
• Collision - a low-poly proxy on every piece, exported as UCX_ collision
    inside the FBX (Unreal picks it up automatically) and as .obj for Unity and   Godot. Decimated rather than hulled, so doorways stay passable.
• LODs - _LOD1 and _LOD2 on every piece over 3 k triangles, named so
    Unreal groups them on import.
• Lightmap UVs - a second, non-overlapping UV channel ready for baked lighting.
• Three formats - native .blend, .fbx and  .glb (the glTF carries the
    full PBR set embedded).

What's inside

20 modular assets: walls, floors, stairs, an octagonal column, a groin vault, battlements, a parapet walkway, a floor hatch, a torch sconce, a portcullis and props (barrel, crate, tavern table, bench, banner). Plus a 6 × 6 m demo keep, a grid overview of every piece, a lit diorama, per-piece previews, an engine import guide and a full asset list with dimensions and pivots.

Style

Flat-shaded, chunky, hand-cut stone: beveled edges, jittered block courses, worn overhangs and uneven flagstones. Textured but stylized — reads beautifully in a low-poly or stylized game, and is a clean base for hand-painting over.

One honest note

FBX has no standard metallic/roughness slot, so the FBX carries Base Color and Normal; the ORM map is included for you to hook into your engine material (Unreal: R→AO, G→Roughness, B→Metallic). If you want a zero-setup PBR import, use the .glb — it has everything embedded. Full steps for Unreal, Unity and Godot are in docs/ENGINE_IMPORT.md.
