Is the Flags 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), 175 KB: 2,320 triangles, 6,960 vertices and 13 materials, modelled in metres at 12 m × 8.3 m × 1.3 m.

It ships as a static mesh. Its 5 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 Flags 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.

Flags

A low-poly trackside flagpole bank: five staggered poles rise from a grass planter bed with kerb-striped coping, each flying a rippled flag, with the black-and-white chequered flag on the tallest centre pole.

How it was made

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

Flags for the Racing Circuit 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 Racing Circuit kit (Low-poly style, flat-lowpoly direction): Speed, pit stops and crowds. Use ONLY the kit palette, by name: tarmac #34373d, kerb red and white #f4f1ec, flag colours #988e81, grass #539b3b, tarmac dark #101113, kerb red and white dark #d7cebc, tarmac light #5c5d61, kerb red and white light #f9f8f6, 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 `teamLiveries` (0–1, default 0.5) for the kit's "Team liveries" setting wherever it makes sense on this part, and keep that id.

Note: Size at default params: about 12.3 m wide (X) × 8.25 m tall (Y, to the top of the centre finial) × 1.3 m deep (Z); the planter bed is 11.2 × 1.2 × 0.53 m and the flags are 1.9 × 1.3 m. Origin at the bottom centre, resting on y = 0 on the planter; flags fly towards +X and face ±Z (front is +Z). Static: the ripple is frozen geometry and the GLB carries no clip. The GLB is the default build: 2,320 triangles, 13 meshes, one per part and palette colour; every material is named after its kit palette colour so the kit recolours by name (names repeat across parts because the exporter writes one material per mesh). Team liveries (the kit knob) is the share of side flags flown in flag colours with a white band instead of plain kerb white with a black hoist band, assigned in mirrored pairs from the centre out; the chequered flag never changes. Flagpoles, centre pole height and flag ripple rebuild the model in the viewer only. glb-lint: 0 errors and 5 expected heuristic warnings (duplicate palette material names, non-indexed flat-shaded geometry, nested planter/pole parts counted as overlaps, height above the direction's 1 m reference). The kit's plan-check rejects the hyphenated library part ids (its regex allows no hyphen in the first segment); a de-hyphenated copy of the plan passes.

About the Flags 3D model

Flags is a free low-poly 3D model from the Racing Circuit set. It measures 12 m × 8.3 m × 1.3 m (W × H × D) at real-world scale and is built from 2,320 triangles across 13 meshes, with 5 named parts. Download the 175 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
