Dripping water
A low-poly rock overhang about 2.5 m tall that curls over a small rimstone pool. Two calcite stalactites drip glowing cyan drops into the pool in a seamless 3-second loop: the drop swells, falls, splashes and sends ripples across the water.

The brief given to 1DesignTool's “3D object” template:
Dripping water for the Cave System 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 Cave System kit (Low-poly style, flat-lowpoly direction): Tunnels, crystals and underground water. Use ONLY the kit palette, by name: stone grey #757e8a, crystal cyan #20c6df, moss #55743e, torch amber #ec9c13, stone grey dark #525860, crystal cyan dark #168a9c, stone grey light #a3a5a8, crystal cyan light #67d4e4, 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 `crystalColour` (0–1, default 0.5) for the kit's "Crystal colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 1.7 m wide × 2.45 m deep × 2.55 m tall. The rock arm's underside is about 1.85 m up, the main drip stalactite is 0.5 m long, and the water sits 0.13 m above the floor in a pool about 0.8 m across. Origin is at the bottom centre and the front faces +Z. The GLB has 1,599 triangles in 25 meshes. three-check's 1,889 figure includes the viewer's staging ground, which is not exported. Animation: one 3 s seamless clip ('scene-motion', 48 channels) moves only the drop, splash and ripple nodes. The rock, stalactites, basin, water and crystals never move. Each drop node sits exactly at its stalactite tip and grows from there, falls by translation and collapses to scale ~0 on impact. Splash and ripple nodes sit at the impact point on the water; ripples rise, spread and sink back under the water sheet. Hidden phases use near-zero scale or sit just under the water rather than toggling visibility. The two drips run out of phase. Drops are drawn about 1.4× life size so they read at thumbnail scale. The GLB's static node pose is the t = 2 s frame, because three-check exports after its determinism seek. Materials are flat-shaded, roughness 0.95, and named exactly after kit palette colours. The exporter writes one material per mesh, so names repeat: recolour by name. Water, drop and crystal materials carry a mild emissive. crystalColour (the kit's 'Crystal colour') slides the three crystal clusters along crystal cyan dark → crystal cyan → crystal cyan light, with tips one step lighter; it does not change the water. overhangHeight stretches the rock arm, and with it the fall distance. dripLength sets the main drip stalactite (the second one is 0.72×). poolRadius scales the basin, water and ripple reach. Params are baked into the GLB at their defaults and only change geometry when the viewer rebuilds the scene; only the defaults were rendered and checked. glb-lint: 0 errors and 6 warnings, all expected: per-mesh duplicate materials, non-indexed geometry for hard flat facets, nested meshes inside a part, a 'detached' heuristic for the water sheet and the moving drops and splashes, and a scale warning because the 2.5 m piece is above the 1 m reference height. 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 16 ids.
About the Dripping water 3D model
Dripping water is a free animated low-poly 3D model from the Cave System set. It measures 1.7 m × 2.5 m × 2.4 m (W × H × D) at real-world scale and is built from 1,599 triangles across 25 meshes, with 16 named parts and a baked animation (3.0 s). Download the 172 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
- Is the Dripping water 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), 172 KB: 1,599 triangles, 4,797 vertices and 25 materials, modelled in metres at 1.7 m × 2.5 m × 2.4 m.
- Is Dripping water animated?
- Yes — the GLB carries a baked animation (3.0 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 Dripping water 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.
