A modular sci-fi corridor kit on a 2 m grid: floors, ceilings, walls with vents, lights, consoles and pipes, a doorway with working sliding doors, posts and corners for junctions, pipe runs, lights and consoles. Everything snaps together, and a T-junction sample layout is included.

What's included (23 pieces)

• Floors (3): panel, hazard-striped threshold, grate with pipes below
• Ceilings (2): panel, emissive light panel
• Walls (6): panel, vent, light strip, console, pipes, doorway (1.0 × 2.4 m) with wall pockets
• Doors (2): sliding leaves L/R that retract into the doorway pockets
• Junctions (3): post (corners, T and X junctions), inner corner, wall end cap
• Pipes (3): 2 m run, 90° bend, 3 m vertical · Lights (2): wall lamp, beacon · Consoles (2): terminal, console bank
• Formats: GLB, FBX, OBJ/MTL per piece + sample layout GLB + Blender source

Specs

• 2 m grid, 3 m walls, pivots at grid corners on the floor (metres)
• 216–3,132 triangles per piece (29,176 for the whole kit)
• PBR metal/roughness, 7 shared materials with 1024 px maps (normal GL + DX, ORM) and emissive light strips, matches the AssetLoom Sci-Fi Crates pack

Engines

Unity, Unreal Engine and Godot.

Conventions

CONVENTIONS
  Units: metres. Grid: 2 m. Z-up in .blend; GLB/FBX/OBJ exported Y-up. Every piece is placed at a grid corner on the floor (z = 0).
  Floors: 2 x 2 m, walkable top at z = 0 (+3-4 mm anti-slip ribs), slab 0.2 m deep (grate pit 0.6 m).
  Ceilings: 2 x 2 m, underside at z = 3.0 m (light panels hang 7.5 cm), so they sit exactly on the 3 m walls.
  Walls: run along +X from the pivot (0..2 m), 3 m tall, centred on the grid line, everything within y = -0.15..+0.15 m
         (console desk and pipe walls protrude into the room on +Y). Rotate 90/180/270 deg about Z for the other directions.
  Doorway: 1.0 x 2.4 m opening with hollow wall pockets. cor_door_L / cor_door_R are the sliding leaves (0.495 m each): place L at x = 0.5 and
         R at x = 1.5 (same rotation as the doorway); slide L by -0.455 m and R by +0.455 m along the wall to open.
  Posts: centred on a grid intersection - cap wall joints, corners and T/X junctions. cor_wall_corner_inner fills an inner 90 deg corner.
  Pipes: cor_pipe_run_2m spans 2.000 m flange to flange (chain them), cor_pipe_corner bends 90 deg (R 0.5 m), cor_pipe_vertical is 3 m.
  Materials: the same 7 PBR materials as the AssetLoom Sci-Fi Crates pack (1024 px, metal/roughness, normal GL + DX, ORM) + emissive strips.

Blender check (live Blender 5.2.1)

• Grid snapping verified for 13/13 modular pieces (floors and ceilings exactly 2 × 2 m from the corner pivot, walls 0–2 m × 0–3 m, posts centred).
• sliding door leaves closed (in the 1.0 x 2.4 m opening): 0 intersections ✔
• sliding door leaves open (retracted 0.455 m into the wall pockets): 0 intersections ✔
• closed leaves meet with a 10 mm gap: 0 intersections ✔
• cor_wall_panel + cor_wall_vent end-to-end on the 2 m grid (1 mm probe gap): 0 intersections ✔
• cor_wall_light + cor_wall_doorway end-to-end on the 2 m grid (1 mm probe gap): 0 intersections ✔
• cor_wall_console + cor_wall_pipes end-to-end on the 2 m grid (1 mm probe gap): 0 intersections ✔
• floor tiles side by side (1 mm probe gap): 0 intersections ✔
• ceiling sits on top of the 3 m walls (1 mm probe): 0 intersections ✔
• All 23 pieces re-imported from the shipped GLB / FBX / OBJ files with every PBR map resolved; 0 loose / degenerate / open edges.
• The 82-piece sample layout was assembled from the kit in the live session (and is included as a GLB and in the .blend).
