Is the Aerials 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), 100 KB: 1,156 triangles, 3,468 vertices and 21 materials, modelled in metres at 1.9 m × 3.1 m × 1.3 m.

Can I animate Aerials?

It ships as a static mesh. Its 6 named parts are separate nodes, so you can move or animate each one in your engine.

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 Aerials 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.

Aerials

Low-poly rooftop TV aerials: a guyed steel mast on a slab-weighted ballast frame. It carries a large fishbone Yagi aerial at the top, a smaller Yagi turned to a second transmitter and a white satellite dish on a side arm.

How it was made

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

Aerials for the Rooftop District 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. This is one part of the Rooftop District kit (Low-poly style, flat-lowpoly direction): Life above the streets. Use ONLY the kit palette, by name: brick red #c32222, tar grey #757e8a, sunset orange #ed7e1d, water-tower brown #6b4a2e, brick red dark #821717, tar grey dark #525860, brick red light #db5757, tar grey light #a3a5a8, 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 `skylineHeight` (0–1, default 0.5) for the kit's "Skyline height" setting wherever it makes sense on this part, and keep that id.

Note: Size: 1.85 m wide (X) by 1.28 m deep (Z) by 3.06 m tall. It is a 1.2 m square non-penetrating ballast frame on two timber sleepers with four tar slabs. A 60 mm mast is braced by four struts and four guy wires. A 1.75 m Yagi with 6 directors sits at the top along X, a 1.05 m Yagi sits at about two thirds of the height on a 40° bearing, and a 0.6 m dish faces +Z on a side arm. The origin is at the bottom centre and the model rests on y = 0. The exported model has 1,156 triangles in 21 meshes. Every material is named exactly after a kit palette colour; 8 of the 12 are used. The runtime's exporter clones each material per mesh, so the GLB has 21 material slots that carry only those 8 names. The model is static, with no animation clip. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. skylineHeight (the kit's 'Skyline height') sets the mast from 2.2 m at 0 to 3.8 m at 1; the aerials, guy collar and dish move with it. Both param extremes were rendered and passed three-check (1,398 and 1,510 viewer triangles). glb-lint: 0 errors and 5 heuristic warnings. These cover the material count and duplicate names from the per-mesh clones, non-indexed geometry (deliberate flat shading), parts nested on the mast, and a 3 m height against the direction's 1 m reference. Its verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires; three-check accepts them and all 6 survive the GLB reload.

About the Aerials 3D model
