【Blender】古い建物の階段&手すり ジェネレーター 4平面・3構造(ジオメトリノード)| Tidebone
- Digital800 JPY






百年使われてきたような階段を1つのモディファイアで。平面(直線・L字・U字・らせん)、構造(木・石・鋼)、手すり(ろくろ・角・鉄・ガラス・ワイヤー・なし)を選び、階高を入力して Wear スライダーを動かすだけ。踏面の歩行線のすり減り、丸く欠けた段鼻、少しずつ沈んだ段、抜け落ちた手すり子まで再現します。 ■ 内容 ・Wear・Settling・Missing Balusters は実ジオメトリ(踏面のへこみ、段鼻の丸み、欠け)。マテリアルも同じマスクを参照 ・階高に合わせて段数とけあげを自動調整し、最上段が床にぴったり。出力:けあげ、踏面、2R+G の快適値(OKフラグ付き)、手すり子の本数 ・手すり子は長さに合わせて配置し、Max Gap(既定12 cm)より広い隙間なし(踊り場・らせんでも) ・4つの平面(直線、踊り場付きL字・U字、柱まわりのらせん)、Mirror で向きを反転 ・木(ささら桁・蹴込み板)、石のブロック、鋼の背骨+オープン踏板。手すり6種と親柱 ・プロシージャルマテリアル(木・石・鋼・ガラス)、画像テクスチャなし ・同梱:tidebone_altbau_stairs.blend(アセット+補助グループ+マテリアル4種)、アセットカタログ、デモシーン、README、LICENSE.txt ■ ご注意(購入前にご確認ください) ・自由な経路のツールではありません(固定の4平面、L・U字の回り段なし、のこぎり状のささら桁なし)。手すりは各フライトで直線です。 ・ゲーム向けではありません(木製は既定の詳細度で8〜12万三角形。Detail Level 1 や角手すりで軽くなります)。 ・快適値・隙間の値はモデリングの目安で、建築基準のチェックではありません。Cycles のみ確認(EEVEE・GUI は未確認)。 ・テスト:35パラメータケース × 3バージョン、エラー0、頂点・面数一致。ライセンスは1名用です。 ■ 動作環境 Blender 4.2 LTS 以降(4.2.23/4.5.14/5.2.1 でヘッドレステスト済み)。アドオン不要、画像テクスチャ不要、単位はメートル。ツールの表示(入力名)と README は英語です。 ■ 制作について(AI使用の表記) ノードグループとマテリアルは、AIコーディングアシスタント(Claude)で書いた Python スクリプトで Blender 上に構築しました(コードはAI支援)。配布ファイルに含まれるのは標準のジオメトリノードとシェーダーノードだけで、スクリプトは含まれません。商品画像はすべて同梱ノードグループの Blender(Cycles)レンダーで、AI生成画像ではありません。 ■ ライセンス(VN3ではありません) 1ライセンス=1名です(LICENSE.txt)。個人・商用プロジェクトで無制限に使用可(レンダー、アニメ、ゲーム、映像、受託制作)、ロイヤリティフリー。生成・適用したメッシュは成果物(ゲーム等)に含めて配布できます。.blend ファイルやノードグループ自体の再配布・転売・共有・アップロードは禁止です。全文は同梱の LICENSE.txt(英語)。チームでのご利用は BOOTH のメッセージでご相談ください。 ―――――――――― ENGLISH ―――――――――― Stairs that have been walked on for a hundred years – one modifier, four plans, three materials. Tidebone Altbau Stairs builds the staircase for your old house, ruin, loft, cellar or period interior and ages it. Pick a Plan (straight, L-shape, U-shape or spiral), a Style (timber, stone, steel) and a Rail Style (turned, square, iron, glass, cables, none), enter the floor-to-floor height and move the Wear slider: worn walking line, rounded and chipped nosings, settled steps, missing balusters. What's inside - Wear, Settling and Missing Balusters as real geometry (tread dip, nosing rounding, chips); the materials read the same masks - Step count and riser fitted to your floor height; outputs Riser Height, Tread Depth, the 2R+G comfort value (with an OK flag) and the baluster count - Balusters fitted to the length: no gap wider than your Max Gap (12 cm default), also on landings and around the spiral - Four plans (straight, L and U with a landing, spiral around a column), Mirror flips the turn - Timber with stringers and risers, solid stone blocks, open steel treads on a spine; six railing styles with newel posts - Procedural materials (timber, stone, steel, glass) – no image textures - tidebone_altbau_stairs.blend (asset + helper groups + 4 materials), asset catalog, demo scene, README, LICENSE.txt What it is not: not a free-form path tool (four fixed plans, no winders in the L/U corners, no notched saw-tooth stringers); the handrail is straight per flight; not game-ready (timber stairs are 80–120k triangles at the default detail); the comfort and gap values are modelling helpers, not a building-code check; checked in Cycles only (EEVEE and the GUI were not tested). Requirements Blender 4.2 LTS or newer (tested headless with 4.2.23 LTS, 4.5.14 LTS and 5.2.1 LTS: 35 parameter cases each, 0 errors, identical vertex and face counts). No add-ons, no Python at runtime, no image textures. Units: metres. How it was made (AI disclosure): code AI-assisted. The node groups and materials were built in Blender by Python build scripts written with an AI coding assistant (Claude); the shipped file contains only standard Geometry Nodes and shader nodes, no scripts. All product images are Blender (Cycles) renders of the included node groups, not AI-generated images. License (not VN3): One license = one person (LICENSE.txt). Unlimited commercial use in your own renders, animations, games and client work, royalty-free; applied meshes may ship in your end products. You may not resell, share or upload the .blend files or the node groups themselves. Full text: LICENSE.txt in the download.
