Is the Escalator 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 374 KB: 2,272 triangles, 6,816 vertices and 91 materials, modelled in metres at 1.5 m × 4.3 m × 10 m.

Is Escalator animated?

Yes — the GLB carries a baked animation (4.0 s), ready to play with any glTF animation mixer.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Escalator 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Escalator

A low-poly subway station up escalator with steel steps, yellow step noses and black risers. The steps climb at 30° between white balustrades with black handrails, beside a tiled truss with a line-colour band. It comes with a seamless 4 s loop of the steps running.

How it was made

The brief given to 1DesignTool's “3D object” template:

Escalator for the Subway Station kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Subway Station kit (Low-poly style, flat-lowpoly direction): A busy underground stop. Use ONLY the kit palette, by name: tile white #f4f1ec, safety yellow #ffdd33, steel #7e8c9a, line colour #988e81, tile white dark #d7cebc, safety yellow dark #e6bf00, tile white light #f9f8f6, safety yellow light #ffea80, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `lineColour` (0–1, default 0.5) for the kit's "Line colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: 10.36 m long × 1.47 m wide × 4.29 m tall (to the top of the handrails), with a 1.0 m step width and a 3.0 m rise at 30°. The origin is at the bottom centre of the bounds on y = 0. The entry faces +Z and the escalator climbs toward −Z. Low-profile landings keep it on y = 0 with no pit below the floor: the lower tread sits 0.2 m up, reached by an 0.8 m entry ramp, and a tile-white pier carries the top end at 3.2 m. Motion: clip 'scene-motion' is 4 s long. The steps run up at 0.5 m/s, and the whole band advances exactly five 0.4 m pitches per loop. Each step translates only. Its riser (sub-part steps.step_NN.riser) scales in y about the tread underside, from a 6 mm sliver on the flat to full height on the incline, the way real steps separate. The loop is seamless as an image, not node by node: at the wrap, each step jumps back five pitches onto an identical step's start pose. The 5 steps that finish on the hidden return run are the only end poses with no matching start, and they sit inside the truss. Only 26 steps are modelled: the ones that can be seen during a loop. There is no full chain. The truss, balustrades, handrails, landings and pier never move. The handrails are static: no moving belt. 2,272 triangles in 91 meshes. Normals are baked flat (non-indexed). 9 of the 12 kit colours are used, and every material is named exactly after its palette colour. The exporter writes one material per mesh, so palette names repeat: recolour by name. Params are baked into the GLB at their defaults, and only the defaults were rendered and checked. lineColour (the kit's 'Line colour') sets the height of the line-colour band on both sides of the truss (0.04–0.20 m). rise and stepWidth rebuild the geometry when the scene is rebuilt in the viewer. glb-lint: 0 errors and 6 heuristic warnings, all expected. They cover per-mesh duplicate materials, non-indexed flat geometry, deliberate overlaps of the truss blocks, steps flagged as detached because they ride inside the truss, and height above the direction's 1 m reference. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 9 survive the GLB reload.
