Is the Hay bales 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), 137 KB: 1,704 triangles, 5,112 vertices and 12 materials, modelled in metres at 1.1 m × 84 cm × 1.1 m.

Can I animate Hay bales?

It ships as a static mesh. Its 13 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 Hay bales 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.

Hay bales

A low-poly stack of three small square hay bales, two side by side with one on top, each tied with two green twine bands and shedding tufts of loose straw. Festival seating or set dressing, in golden sunset orange.

How it was made

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

Hay bales for the Music Festival 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 Music Festival kit (Low-poly style, flat-lowpoly direction): Stages, tents and mud. Use ONLY the kit palette, by name: tie-dye #988e81, stage black #151619, grass green #3a883a, sunset orange #ed7e1d, tie-dye dark #70685c, stage black dark #090a0b, tie-dye light #b6b3af, stage black light #3a3c40, 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 `genre` (0–1, default 0.5) for the kit's "Genre" setting wherever it makes sense on this part, and keep that id.

Note: Size: each bale is a small square (two-string) bale, 0.46 m wide, 0.36 m tall and 0.90 m long. The default stack is 0.96 m wide, 0.90 m long and 0.73 m tall to the top of the hay. Counting the straw tufts, the overall bounds are 1.12 m × 0.84 m × 1.09 m (x × y × z). Bales lie with their length along Z, so the front (+Z) shows the three cut ends in a pyramid. The origin is at the bottom centre and the bottom bales rest exactly on y = 0; the top bale rests exactly on the two below. The model is static: no animation clip. The GLB has 1704 triangles in 12 meshes. Every face is flat-shaded, and the geometry is non-indexed on purpose so it stays faceted in any engine. Materials are named exactly after kit palette colours: sunset orange (hay), grass green (twine) and warm white (straw). The exporter writes one material per mesh, so each name appears several times: recolour by name. Sunset orange carries the hay because it is the only warm colour in the kit and lights up as golden straw; the greige tie-dye colours read as stone. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. genre (the kit's 'Genre') sets the stack layout: below 0.33 it is a low two-bale bench (acoustic or folk seating), from 0.33 to 0.66 the default two-over-one stack, and from 0.66 up a six-bale 3-2-1 pyramid (stage-side), which adds parts bale_3 to bale_5. baleLength changes the length of every bale. scruff sets how many straw tufts come out of the cut ends, the outer sides and the top bale; at 0 there are no straw parts. jitter adds seeded yaw and offsets to each bale, and the gaps widen with it so neighbouring bales never touch. At the most extreme settings (genre 1, scruff 1, length 1.1 m, jitter 1) the viewer renders 4304 triangles including the staging, which is under the 6000 budget. Both extremes were rendered and inspected. The viewer's exposure is 0.95 instead of the direction's 1.05 so the orange does not wash out to pastel; this affects only the preview, not the GLB. glb-lint: 0 errors and 5 heuristic warnings. One flags the 12 per-mesh materials, which are 3 palette colours. One flags duplicate materials (the same thing). One flags non-indexed primitives (flat shading, on purpose). One flags the straw meshes overlapping their bale's bounding box, because their roots are embedded in the hay. One flags the top bale's twine bands as 'detached'; they sit on the top bale, which rests on the bales below. The verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check rejects the hyphens in the slug-based part ids this library requires; with the ids substituted the plan passes. three-check accepts the real ids, and all 13 survive the GLB reload.
