Is the Entrance 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), 167 KB: 2,028 triangles, 6,084 vertices and 27 materials, modelled in metres at 10 m × 6.5 m × 3.2 m.

Can I animate Entrance?

It ships as a static mesh. Its 33 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 Entrance 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.

Entrance

A low-poly zoo front gate: two thatched timber towers with yellow pennants carry an arched sign-yellow board with a giraffe and acacia cut-out. Turnstile lanes run through the opening, with a striped-awning ticket booth on each side.

How it was made

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

Entrance for the Zoo 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 Zoo kit (Low-poly style, flat-lowpoly direction): Enclosures and winding paths. Use ONLY the kit palette, by name: leaf green #3a883a, sand #d1bd94, timber #765232, sign yellow #eecd2b, leaf green dark #235223, sand dark #ba9c5e, leaf green light #5db15d, sand light #e6ddcb, 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 `habitatMix` (0–1, default 0.5) for the kit's "Habitat mix" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale in metres, +Y up, front faces +Z, origin at the bottom centre, resting on y = 0. Overall bounds are 10.2 m wide (x), 6.53 m tall to the pennant pole tips and 3.2 m deep (z). The forecourt slab is 0.1 m thick, the walk-through opening is 3.6 m wide, the towers stand 4.6 m to the cap plates with thatch above, and the ticket booths are 1.6 x 1.8 m with 2.3 m walls. The model has 2028 triangles, is static and has no animation clip. Every GLB material is named after its Zoo kit palette colour. The exporter writes one material per mesh, so a name such as 'sand dark' appears on several materials with identical values; recolouring by name updates them all. Geometry is flat-shaded and non-indexed on purpose, so facet normals survive in Godot, Unity and Blender. The params (habitatMix, openingWidth, towerHeight, lanes) rebuild the model in the 1DesignTool viewer; the GLB is the default build (habitatMix 0.5: four bushes, four sand mounds with rocks, three creeper clumps). habitatMix 0 gives sand mounds and rocks only; 1 gives bushes in every slot plus creeper on the beam and towers. lanes is capped by the opening width so each lane stays at least 0.6 m wide. glb-lint reports 0 errors; its warnings are heuristics for this kind of build (duplicate same-name materials, non-indexed flat geometry, nested parts, scale vs a 1 m reference). The kit's plan-check part-id pattern does not allow the hyphen in the required 'zoo-entrance' slug; the plan passes once that is set aside.

About the Entrance 3D model

Entrance is a free low-poly 3D model from the Zoo set. It measures 10 m × 6.5 m × 3.2 m (W × H × D) at real-world scale and is built from 2,028 triangles across 27 meshes, with 33 named parts. Download the 167 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
