Is the Columns 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), 205 KB: 2,644 triangles, 7,932 vertices and 20 materials, modelled in metres at 12 m × 7.4 m × 3.4 m.

Can I animate Columns?

It ships as a static mesh. Its 13 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 Columns 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.

Columns

Three low-poly Greek marble columns on a shared stepped plinth, one for each classical order: a stout fluted Doric column, a slender Ionic column with scroll volutes, and a Corinthian column with an acanthus-leaf capital. A slider takes the marble from bare to painted.

How it was made

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

Columns for the Greek Acropolis 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 Greek Acropolis kit (Low-poly style, flat-lowpoly direction): White temples on a rocky hill. Use ONLY the kit palette, by name: marble #e8e6e3, aegean blue #2e67b8, olive green #3a883a, terracotta #be5937, marble dark #c6bfb9, aegean blue dark #1f457a, marble light #f8f7f7, aegean blue light #6190d1, 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 `paintedOrBareMarble` (0–1, default 0.5) for the kit's "Painted or bare marble" setting wherever it makes sense on this part, and keep that id.

Note: Size: 11.8 m wide (x) by 3.4 m deep (z) over the two-step plinth, 7.4 m tall: each column is 7.0 m from the plinth top (0.4 m) to the top of its abacus, so all three carry an entablature at the same line. Diameters follow each order's proportions: Doric 1.28 m at the foot, Ionic 0.80 m, Corinthian 0.72 m. Front (volute faces) is +Z, origin at the bottom centre on y = 0. The exported model has 2,644 triangles in 20 meshes (merged per part and colour) and no animation clip; normals are baked flat (non-indexed). Every material is named exactly after its kit palette colour; the default GLB uses 7 of the 12 kit colours (aegean blue light, warm white, mid grey, soot black and dark wood are unused). The exporter writes one material per mesh, so a colour name can repeat: recolour by name. paintedOrBareMarble works in steps rather than blending: 0–0.25 is bare marble; from 0.25 the Doric necking and Corinthian rosettes turn terracotta and the Ionic volute eyes dark blue; from 0.5 (the default and the GLB) the Ionic cushion is aegean blue and the acanthus olive green; from 0.75 the abaci turn dark blue and the echinus terracotta. columnHeight scales each column uniformly (keeping its order's proportions); spacing moves the outer columns and resizes the plinth; flutes sets the flute count on all three shafts. Params change geometry only when the scene is rebuilt in the viewer; the GLB is baked at the defaults. glb-lint: 0 errors and 6 heuristic warnings — duplicate materials (per-mesh materials), unindexed geometry (flat shading on purpose), sibling overlap (bases, shafts and capitals nest on purpose), one 'detached' part (the Doric capital rests on its shaft, a separate part), scale (compared with the direction's 1 m reference), plus its standing 'no requirements contract' UNVERIFIED verdict. three-check passes 24 of 24; its triangle figure is slightly higher because it includes the viewer's ground disc. plan-check passes except for its part-id regex, which rejects the hyphens that this library's slug-based ids need; the same plan with the slug de-hyphenated passes.
