Is the Fallen logs 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), 196 KB: 2,484 triangles, 7,452 vertices and 23 materials, modelled in metres at 4.0 m × 92 cm × 2.0 m.

Can I animate Fallen logs?

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 Fallen logs 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.

Fallen logs

A low-poly heap of dead acacia wood for the Savanna kit: a long dark trunk with a broken root plate and a hollow snapped end, a second log fallen across it and a short broken section in front, all with pale heartwood ends, red termite mud and grass tufts at the bases.

How it was made

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

Fallen logs for the Savanna 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 Savanna kit (Low-poly style, flat-lowpoly direction): Golden grass and big animals. Use ONLY the kit palette, by name: straw gold #d0a225, acacia green #3a883a, earth red #c32222, dusk purple #572e6b, straw gold dark #8f7019, acacia green dark #235223, straw gold light #debd63, acacia 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 `dryOrWetSeason` (0–1, default 0.5) for the kit's "Dry or wet season" setting wherever it makes sense on this part, and keep that id.

Note: Size: 3.98 m long (X), 1.98 m deep (Z) and 0.92 m tall where the crossed log's raised end rises behind the trunk. The trunk is about 0.48 m across, flaring at the root plate, which is believable for a fallen acacia. The origin is at the footprint centre, the bottom rests on y = 0 and the front faces +Z. Every log's underside lies on the ground. The crossed log's height above the trunk is solved so the two surfaces just touch. The GLB has 2484 triangles in 23 meshes, is static and carries no animation clip. three-check's figure (about 2.7k) is higher because it includes the viewer's staging ground, which is not exported. Every material is named exactly after a kit palette colour. 10 of the 12 are used; dusk purple and warm white have no place on deadwood. The exporter writes one material per mesh, so names like 'dark wood' repeat; recolour by name. dryOrWetSeason (the kit's 'Dry or wet season'): toward 0, more bark is bleached grey, the tufts turn golden and there is more termite mud; toward 1, the tufts turn green and up to 4 moss patches appear. length and girth size the trunk, and the other logs follow. logCount removes the short section, then the crossed log. Params are baked into the GLB at their defaults and change the geometry only when the scene is rebuilt in the viewer. Only the defaults were rendered and checked. The viewer uses exposure 0.62 rather than the direction's 1.05; this does not affect the GLB. glb-lint: 0 errors and 5 warnings, all expected. They are materials over the soft cap of 10 (repeated palette names from the per-mesh export), materials with duplicate names for the same reason, non-indexed geometry used on purpose for flat facets, overlapping boxes between colour meshes of the same part, and a 'detached' flag for the mud and moss, which are seated into the bark. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen. The same plan with the slug de-hyphenated passes. three-check and the GLB reload keep all 9 ids.
