Is the River tiles 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), 630 KB: 8,590 triangles, 25,770 vertices and 29 materials, modelled in metres at 4.0 m × 1.8 m × 4.0 m.

Can I animate River tiles?

It ships as a static mesh. Its 10 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 River tiles 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.

River tiles

A low-poly 4 × 4 m River Delta ground tile: a slow blue river winds in a gentle S between grassy mud banks, with a bamboo fish-trap fence, reeds with cattails, nipa palms, stones, a drift log and floating water hyacinths. It chains front-to-back with itself and meets other bank tiles flush at the sides.

How it was made

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

River tiles for the River Delta 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. Make it a ground piece on an exact 4 × 4 m footprint with flat edges at y = 0 that tile seamlessly with its neighbours in every direction; origin at the tile centre. This is one part of the River Delta kit (Low-poly style, flat-lowpoly direction): Stilt houses and floating trade. Use ONLY the kit palette, by name: muddy brown #43372d, palm green #3a883a, bright boat colours #b39d80, sky blue #2e67b8, muddy brown dark #15120e, palm green dark #235223, muddy brown light #6d5d50, palm green light #5db15d, 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 `waterLevel` (0–1, default 0.5) for the kit's "Water level" setting wherever it makes sense on this part, and keep that id.

Note: Size: an exact 4 × 4 m footprint (x and z from −2 to +2) and 1.85 m tall to the tallest nipa frond. The origin is at the tile centre on the bottom; the slab rests on y = 0 and the front faces +Z. The bank tops are 0.8 m high; the river is 2.3 m wide bank to bank, its bed is 0.12 m above the base, and the water stands 0.45 m high at the default level. Tiling: the river centreline is x = A·sin(πz/2), so the channel cross-section is identical on the front and back edges and river tiles chain front-to-back. Bank relief fades to zero 0.3 m inside every border, so both side edges are flat at 0.8 m and meet any other bank tile flush. Neighbours must use the same waterLevel, riverWidth and meander. This tile does not join edge-to-edge with the open-water floating-docks tile: that tile is water across its whole width. waterLevel (the kit's 'Water level') moves the water surface from 0.25 m to 0.65 m, which is the same range the floating docks use. The wet-mud tide band, the stake tide bands and the floating hyacinths follow it, and reeds on the upper slope stand in the water when the level is high. riverWidth sets the bank-to-bank width (1.8 to 2.6 m), meander sets the S amplitude (0 to 0.4 m), and reeds thins out the reed clumps (0 means none). Params are baked into the GLB at their defaults. The GLB has 8,590 triangles in 29 meshes. It is static and carries no animation clip; three-check's 8.9k figure includes the viewer's staging ground, which is not exported. Every material is named exactly after a kit palette colour (10 of the 12; bright boat colours and soot black are unused). The exporter writes one material per mesh, so some names appear more than once; recolour by name. The water is an opaque closed body, not a transparent plane. glb-lint reports 0 errors and only heuristic warnings: non-indexed flat-shaded primitives, overlapping bank colour meshes from the same slab, and the stones flagged as detached even though they are sunk into the mud. plan-check rejects the hyphenated slug part ids the library requires; a copy with the ids de-hyphenated passes, and three-check accepts the hyphenated ids.
