World3DWorks 日本の地方都市 建物セット Vol.1 / Japanese Local City Building Set Vol.1【Blender / Unity / FBX】

日本語

日本の地方都市をイメージした商業・事務所系建築5棟（Building 01〜05）の3D建物セットです。正面だけでなく、左右側面・背面・屋上設備・外から見える範囲の内部表現を収録しています。

収録形式：Building 01〜05のBlender High品質Source 5件 / FBX 15件（5棟 × High・Mid・Low） / UnityPackage（LOD Group設定済みPrefab 5件、Demo Scene 2件：通常DEMO 1件、LOD_DEMO 1件）

実測Triangle数（High / Mid / Low）：

Building 01：220,240 / 143,100 / 106,592

Building 02：359,940 / 233,926 / 136,194

Building 03：91,192 / 64,754 / 51,882

Building 04：204,060 / 139,350 / 105,377

Building 05：213,152 / 141,167 / 82,449

MidはLOD1・中距離向け、LowはLOD2・遠距離表示向けの軽量版であり、極端なローポリゴン専用モデルではありません。UnityではLOD Groupにより距離に応じて自動的に切り替わるため、手動交換は不要です。

Unity版は全5棟についてLOD0（High）・LOD1（Mid）・LOD2（Low）の3段階モデル、LOD Group設定済みPrefab、建物外郭用Box Colliderを収録しています。通常展示用の LocalCityBuildingSetVol1_Demo.unity と、LOD動作確認用の LocalCityBuildingSetVol1_LOD_Demo.unity を同梱しています。通常DEMOはPrefab配置・外観・Material・Lighting・全体構成の確認用です。LOD_DEMOはカメラ距離に応じたLOD0 High / LOD1 Mid / LOD2 Lowの自動切替確認用です。LOD切替値は0.55 / 0.25 / 0.05です。Colliderは外郭用で、室内探索、扉開閉、屋上設備個別Colliderには対応していません。

Blender 5.0.1で確認済み。FBX Export／再Import確認済み。Unity 6000.3.5f2のmacOS検証用ProjectでImport、5 Prefab、LOD Group、Collider、Demo Sceneを確認済みです。WindowsでのLOD・Collider詳細実機確認は未実施です。VRChat実機動作およびUnreal Engineでの動作は未検証です。

主要看板・表示文字はBlender版でText Objectとして編集できます。FBX / Unityでは完成表示用Meshです。商用利用・改変可。素材データそのものの再配布・再販売、AI学習等は禁止です。詳細な利用条件は同梱の日本語版LICENSE_JA.mdを参照してください。

English

A set of five commercial and office buildings (Building 01–05) inspired by Japanese local-city architecture. The assets include front, side, rear, rooftop-equipment, and limited visible-interior detail.

Contents: 5 high-quality Blender sources for Building 01–05 / 15 FBX files (5 buildings × High, Mid, and Low) / UnityPackage with 5 configured LOD Group Prefabs and 2 Demo Scenes: one standard Demo Scene and one LOD_DEMO Scene.

Measured triangle counts (High / Mid / Low):

Building 01: 220,240 / 143,100 / 106,592

Building 02: 359,940 / 233,926 / 136,194

Building 03: 91,192 / 64,754 / 51,882

Building 04: 204,060 / 139,350 / 105,377

Building 05: 213,152 / 141,167 / 82,449

Mid is intended for LOD1 medium-distance display, while Low is a lighter LOD2 variant for distant display rather than an extremely low-poly model. Unity switches between them automatically through the configured LOD Groups; manual model replacement is not required.

All five Unity Prefabs include LOD0 High, LOD1 Mid, and LOD2 Low models, configured LOD Groups, and lightweight building-envelope Box Colliders. The LocalCityBuildingSetVol1_Demo.unity scene is intended for checking Prefab placement, appearance, materials, lighting, and the overall presentation. The LocalCityBuildingSetVol1_LOD_Demo.unity scene is intended for testing automatic LOD0 High / LOD1 Mid / LOD2 Low switching based on camera distance. Transition values are 0.55 / 0.25 / 0.05. The Colliders block the exterior envelopes; interior exploration, operable doors, and individual rooftop-equipment colliders are not included.

Verified in Blender 5.0.1, including FBX export and re-import. Import, five Prefabs, LOD Groups, Colliders, and the Demo Scene were verified in a macOS test project using Unity 6000.3.5f2. Detailed Windows LOD/collision testing has not yet been performed. VRChat runtime behavior and Unreal Engine operation have not been verified.
