Is the Greenhouse 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), 168 KB: 2,086 triangles, 6,258 vertices and 25 materials, modelled in metres at 3.7 m × 3.2 m × 4.1 m.

Can I animate Greenhouse?

It ships as a static mesh. Its 9 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 Greenhouse 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.

Greenhouse

A low-poly rooftop greenhouse: a white-framed gable glasshouse on a brick knee wall, with an orange glazed door, two roof vents propped open, a gutter and downpipe feeding a wooden water butt, and raised beds of blooms inside.

How it was made

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

Greenhouse 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 at the defaults: 3.0 m wide across the brick knee wall (3.7 m including the gutters and the water butt at the front-right corner), 4.0 m long and 3.0 m to the ridge, or 3.25 m to the top of the finials. The eaves are at 2.2 m. The origin is at the bottom centre of the footprint, the model rests on y = 0 and the door gable faces +Z. The GLB has 2,616 triangles and is static, with no animation clip. Every material is named exactly after a kit palette colour. 11 of the 12 are used; brick red light is not. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. The glass is tar grey light at 24% opacity with alpha blending. Some engines sort transparent surfaces differently, which can change how the glass layers look. 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') raises the eaves from 1.9 m to 2.5 m, and the ridge rises with them. length sets 3 to 6 one-metre bays. ventOpen lifts the two roof lights from 0 to 40 degrees. Only the default params were rendered and checked; the extremes were not captured. glb-lint: 0 errors and 6 heuristic warnings. Two come from the per-mesh materials (duplicate material sets). One flags non-indexed geometry, which is deliberate flat shading. One flags nested overlaps in the brick base. One flags parts as 'detached' (the coping, glass and door handle), though each rests on a neighbour. One flags the 3.25 m height against a generic 1 m reference. The 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. With the ids substituted it passes. three-check accepts the real ids, and all 9 survive the GLB reload.

About the Greenhouse 3D model
