Muted and stylized, its textures made in code, all on a 2 m grid with 4 m storeys, with the seamless textures they tile from. A prefab per piece with colliders, the pack's lit shader for Built-in and URP. Cut from Low Poly Sewers (http://u3d.as/4d5H), the full kit of 135 props with 26 working machines, a pumping station, lamps, signs, debris and a sewer to pump out.What's insideWalls (21): brick plain, with a tide line, stained, mossy, rendered and repaired in concrete, lettered for the outfall, the chamber, the overflow and deep water; a pumping station's glazed brick, plain and over brown; half, low and broken walls, one with a hole; posts for the corners, a brick pier and a fluted iron column.Openings (9): sewer and station doorways and wide doorways, an arch, a culvert across a channel, an outfall into the dark, a round inlet and a barred grille with daylight behind.Tunnels (6): brick-vaulted tunnels clean, stained and mossy, benched either side of their flow, an end, an end with a pipe through it, and the portal wall where one meets a chamber. The portal's colliders follow its arch, leaving the opening clear to walk through.Floors, ceilings and stairs (13): blue brick paving plain, wet and silted, setts, a station's red tiles, a gully and an upper floor; jack-arch vaults plain and stained, a flat ceiling, a street grating with daylight down it and the station's; brick stairs a storey up.Channels (8): straight, end, corner, tee, cross, a weir, grated over and a gutter, 1.6 m wide and 0.6 m deep, their copings at the floor.Water (6): a channel's flow clear and foul, a flood over a floor, a puddle, drips falling from the vault and a trickle from a pipe, the last two moving.Ways across (11): grating, plank and brick footbridges, iron railings long and short and a chain, step irons short and tall, a ladder and steps down into a channel, a wall handrail.Seamless textures (brick, render, floors, ceilings, tunnel and channel lining; 128 px a metre) as their own PNGs, for your own geometry, and an icon per piece.One 2048x2048 texture atlas filtered with mipmaps, the occlusion baked into the vertex colours, real-world scale.Built on a gridEverything snaps to a 2 m grid with 4 m storeys: a wall is 2 m long and 0.25 m thick, a floor or a channel covers a 2 x 2 m cell, and a tunnel piece runs 2 m along its cell. A channel's copings are at the floor, so the cells beside it are its walkways; the stairs climb a storey over three cells to the upper floor. Low Poly Industrial Facility's and Low Poly Bunker's pieces snap to the same points.Unity 6.3A .unitypackage with a prefab per piece (colliders, and the water's looping clips), the pack's lit shader for Built-in and URP (baked occlusion, soft light, shadows and fog) and a demo scene.Drag the drips or trickle prefab into a scene and their water animation starts automatically.74 props, 8 to 1672 triangles each (13197 in all); the full list with sizes is in Documentation.txt.Textures: 32 PNG (2 at 2048x2048, 30 at 128x128), filtered with mipmaps, colour only: the shading is baked into vertex colours, so no normal maps.UV mapped, no LODs (one low-poly mesh per part), no rig: 2 props move their parts in 2 animations (Legacy Animation clips).Real-world scale, 1 unit = 1 m, pivots on the floor or wall they rest against.A prefab per prop with box colliders on its parts, one material, a demo scene.Render pipelines: Built-in and URP: every material uses the pack's own lit shader, with a SubShader for each. Not HDRP, where the materials show magenta until given an HDRP Lit shader.Unity 6.3 or later, in the Built-in pipeline or URP.A Documentation.txt in the package's folder says what is where and how to use it.Code written with the help of AI (Anthropic's Claude); no generative image, 3D or audio model.
