Is the Hot spring pools 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), 241 KB: 3,211 triangles, 9,633 vertices and 16 materials, modelled in metres at 4.2 m × 2.4 m × 5.3 m.

Can I animate Hot spring pools?

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 Hot spring pools 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.

Hot spring pools

Low-poly volcanic hot spring: three stepped white sinter terraces with iron-streaked fronts, each holding a pool of milky water that spills into the one below, with a steaming geyser cone in the top pool, basalt boulders, fern tufts and a wooden duckboard.

How it was made

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

Hot spring pools for the Volcano Island 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 Volcano Island kit (Low-poly style, flat-lowpoly direction): A smoking peak over black sand. Use ONLY the kit palette, by name: basalt black #151619, lava orange #ed7e1d, ash grey #757e8a, jungle green #3a883a, basalt black dark #090a0b, lava orange dark #af590e, basalt black light #3a3c40, lava orange light #eea668, 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 `eruptionStage` (0–1, default 0.5) for the kit's "Eruption stage" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 4.2 m wide × 5.3 m deep including the duckboard; the bottom pool is 3.2 m wide, the three terraces step up 0.35 m each to a 1.05 m top rim, and the geyser steam reaches 2.36 m (the full bounding-box height). Origin at the bottom centre, resting on y = 0, terraces stepping down toward +Z (the front). eruptionStage (the kit's 'Eruption stage') drives the heat read: at 0 the pools carry no steam and the curtains are mostly white; as it rises the pool wisps and geyser column grow taller, the geyser cone rises, the iron streaks widen, and above 0.75 the streaks turn lava orange and the geyser throat glows. poolCount (2–4) adds or removes terraces, terraceStep (0.2–0.6 m) sets each step's rise, poolWidth (2.4–4.2 m) scales the footprint. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. The GLB has 3,211 triangles in 16 meshes and no animation clip. Every material is named exactly after a kit palette colour (10 of 12 used at the default stage; lava orange appears above 0.75, lava orange dark is unused). The exporter writes one material per mesh, so some names repeat: recolour by name. Geometry is non-indexed on purpose for flat facets. glb-lint: 0 errors, 6 expected heuristic warnings (material count/duplicates from per-part per-colour meshes, non-indexed, nested part overlaps, water/spillway/geyser/steam flagged 'detached' though they sit inside the terraces, height vs a 1 m reference); its verdict reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects only the hyphenated library part ids (its regex allows no hyphen); the same plan de-hyphenated passes. Viewer-only staging: exposure 0.6 and a staging ground that is not in the GLB.
