Multi-style Low-poly industry kit for city builders: 550+ prefabs:
modular buildings, roads, rail, bridges and power lines you paint onto the terrain. Includes full source code, URP and HDRP.Unity 6.3 LTS and newer.URP: works right after import.HDRP: import the bundled add-on with Tools > Paryonix > Setup. Built-in: **not supported**Smoke needs the VFX Graph package (optional).Importing changes no project settings; the demo uses its own pipeline settings only in Play mode.Roads on Unity terrain need Terrain Holes on (Setup > Check pipeline settings).Gridworks is a low-poly asset kit for city-building, tycoon and strategy games with an industrial focus. It covers power plants, a steel mill, a nuclear site, a refinery, a hydro dam, rail yards and the surrounding town, with around 560 prefabs.A large part of the kit is procedural. The 62 modular buildings can be extended bay by bay and floor by floor - roads, rail, bridges, power lines, fences and pipe racks are painted directly onto the terrain in the Scene view. Junctions, crossings, slopes and bridge approaches are generated automatically. Full source code and a runtime API are included, so the same tools can be used inside your game.**Multi-Style** Procedural buildingsAll assets can be styled and colored using one of 6 style presets. Custom styles and color sheets can be added. Industrial halls, offices, power plant buildings and steel-mill structures are assembled from repeating bays and floors. Bays and floors are added with handles in the Scene view or from the Inspector; facades, roofs and stairs update immediately, every change can be undone. At runtime, the size is controlled through the Bays and Floors properties.Procedural roads, rail and bridgesGrid-based roads on 14 m tiles in four styles, including median and gutter-channel variants. Corners, T-junctions and crossings are created automatically, roundabouts are placed with a single click.Country roads, gravel roads, footpaths follow freely drawn curves and connect to the road grid.Rail networks with switches, three-way switches, diamond crossings, yard fans and sidings. Where a track crosses a road, a level crossing with movable booms is added.All routes follow the terrain on slopes of up to 30°, with embankments, retaining walls and foundations added where required. Parallel tracks share a common embankment.Eleven bridge types, from timber trestles to suspension bridges. A bridge is placed by clicking both ends; its approaches are graded automatically, and the piers are kept clear of roads and tracks below.Power lines, fences and pipe racks use the same workflow. Pylons are placed clear of the roads they cross, lines can branch at poles.An eraser removes individual tiles, and each edit is a single undo step. Only the affected parts are rebuilt, which keeps large maps responsive.Compatible with Unity Terrain: trees and grass beneath a new road are removed and restored when the road is deleted.The generators also run in builds, so players can build roads and rail in your game.Included content (prefabs per category)Power Buildings 20 · Power Units 29 · Cooling Towers 15 · Chimneys 12 · Nuclear 11 · Steel Mill 13 · Refinery 27 · Tanks 24 · Pipes 10 · Pipeways 42 · Electrical 27 · Industrial 21 · Offices & Civic 19 · Rail 19 · Roads 23 · Vehicles 53 · Cargo 55 · Street 38 · Site 13 · Details 25 · Roof Details 28 · Nature 35Highlights include a blast furnace with hot-blast stoves, a coke oven battery, PWR reactor buildings, a combined-cycle power block, natural-draught cooling towers, a stacker-reclaimer, refinery units and tank farms, a hydro barrage and an arch dam, locomotives and rail cars, and 53 vehicles ranging from cars to mobile cranes.**Please note**The package does not include a traffic system. Vehicles, trains and machinery are static props without driving or simulation logic.The models are not animated: there are no rigs or animation clips. Cranes, barriers and gates have movable parts that can be set in the editor or driven from your own scripts, and wind turbine rotors turn on their own.Third-party contentAsset uses HDRI environments from Poly Haven under CC0; see Third-Party Notices.txt file in package for details.Features559 prefabs in 22 categories, from cooling towers and blast furnaces down to pallets and traffic cones62 modular buildings with adjustable bays and floorsPaint tools for roads, rail, country roads, bridges, power lines, fences, pipe racks, ground plots and plantsSix texture styles (Trim, Classic, Worn, Victorian, Vivid, Clean), switchable for the whole scene or a single objectFive colour moods (Default, Sunny, Pastel, Autumn, Winter), 11 colour themes, or your own coloursA wear slider from factory-new to rusty and soot-stained, without extra texturesCustom Models tool: give the materials of your own FBX models pack colours so they match the styles, moods and wearDay and night with sun and moon, windows that light up one by one, street lamps, floodlights and aviation lightsSmoke and steam on chimneys, cooling towers and flare stacks (VFX Graph)Moving parts: stacker-reclaimer, ore-bridge crane, wind turbines, barriers, rising bollards and gatesRuntime API for time of day, style, mood, quality, buildings and the generatorsAll source code included (tools, runtime and shaders)Industry Demo scene for URP and HDRP with a tour camera and free flightCollision meshes on 545 prefabsRender pipelinesURP: yes, the base package.
