Flickering fire
A low-poly campsite fire: a teepee of charred logs in a round steel fire ring, with a crown of orange flame tongues round a warm-white core that flicker on a seamless 4-second loop. Part of the Campground kit.

The brief given to 1DesignTool's “3D object” template:
Flickering fire for the Campground 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. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Campground kit (Low-poly style, flat-lowpoly direction): Tents, vans and a lake. Use ONLY the kit palette, by name: forest green #3a883a, canvas tan #bf9769, flame orange #ed7e1d, lake blue #2e67b8, forest green dark #235223, canvas tan dark #9a7142, forest green light #5db15d, canvas tan light #d2bca2, 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 `season` (0–1, default 0.5) for the kit's "Season" setting wherever it makes sense on this part, and keep that id.

Note: Size at the defaults: the steel fire ring is about 0.94 m across and 0.2 m tall to its lip; the flames reach about 0.69 m; the grass tufts round it widen the footprint to about 1.4 m. The origin is at the bottom centre and the model rests on y = 0, with the front facing +Z. The GLB has 1,840 triangles in 16 meshes and one 4 s loop clip, 'scene-motion'. Each flame part (main flame, core and five tongues) sways and stretches about its own root in the ash mound, using rotation plus a volume-preserving scale. The main flame and the core also spin one turn each way per loop. The ring, ash, embers, logs and grass do not move. The export was taken after a seek, so the static node pose in the GLB is the t = 2 s frame. Every material is named exactly after a kit palette colour. The flame, ember and core materials are emissive copies of flame orange and warm white with the same names. The exporter also writes one material per mesh, so names repeat; recolour by name. Lake blue is not used on this part. season (the kit's 'Season'; 0 = early spring, 0.5 = high summer, 1 = late autumn) changes the grass colour in three steps (fresh green, green, straw). It scatters fallen leaves from late summer on and makes the flames up to 15% taller toward either end of the season, for colder nights. flameHeight scales the flame crown. flicker only scales the motion amplitude, and 0 gives still flames. logCount (3–7) sets the logs in the teepee. Params are baked into the GLB at their defaults and change the geometry only when the scene is rebuilt in the viewer. The defaults and one extreme (season 1, flameHeight 0.9, 7 logs; 2,454 tris) passed three-check. glb-lint reports 0 errors and some heuristic warnings, which are expected: the flame parts are 'detached' because each is its own pivoted part rooted inside the ash mound, and the 16 materials come from one material per mesh. Its verdict reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects the hyphenated slug part ids by regex, so it was verified PASS on a copy with the hyphens stripped; three-check uses the real ids. Viewer-only staging (ground, sun rig, exposure 0.62) is not in the GLB.
About the Flickering fire 3D model
Flickering fire is a free animated low-poly 3D model from the Campground set. It measures 1.3 m × 69 cm × 1.2 m (W × H × D) at real-world scale and is built from 1,840 triangles across 16 meshes, with 12 named parts and a baked animation (4.0 s). Download the 193 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
- Is the Flickering fire 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), 193 KB: 1,840 triangles, 5,520 vertices and 16 materials, modelled in metres at 1.3 m × 69 cm × 1.2 m.
- Is Flickering fire animated?
- Yes — the GLB carries a baked animation (4.0 s), ready to play with any glTF animation mixer.
- 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 Flickering fire 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.
