# 日本語 日本の地方都市をイメージした無料の建物3Dアセット「Sample Building A」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:Blender High品質Source 1件 / FBX 3件(High・Mid・Low) / UnityPackage(LOD Group設定済みPrefab 1件、Demo Scene 2件:通常DEMO 1件、LOD_DEMO 1件) 実測Triangle数(High / Mid / Low):236,600 / 150,290 / 97,942。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版には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、通常展示用の SampleBuildingA_Demo.unity、LOD動作確認用の SampleBuildingA_LOD_Demo.unity を収録しています。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。Unity 6000.3.5f2のmacOS検証用ProjectでImport、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 Sample Building A is a free 3D building asset inspired by Japanese local-city architecture. It includes the front, both sides, rear, rooftop equipment, and limited interior details visible from outside. Contents: one high-quality Blender source / 3 FBX files (High, Mid, and Low) / UnityPackage with 1 configured LOD Group Prefab and 2 Demo Scenes: one standard Demo Scene and one LOD_DEMO Scene. Measured triangle counts (High / Mid / Low): 236,600 / 150,290 / 97,942. 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 Group; manual model replacement is not required. The Unity version includes three detail levels—LOD0 High, LOD1 Mid, and LOD2 Low—an LOD Group Prefab, a lightweight building-envelope Box Collider, the SampleBuildingA_Demo.unity standard presentation scene, and the SampleBuildingA_LOD_Demo.unity LOD test scene. The standard Demo Scene is intended for checking Prefab placement, appearance, materials, lighting, and the overall presentation. The LOD_DEMO 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 Collider blocks the exterior envelope; interior exploration, operable doors, and individual rooftop-equipment colliders are not included. Verified in Blender 5.0.1. Import, Prefab, LOD Group, Collider, and 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. Major sign text is editable as Text Objects in the Blender version. In FBX / Unity it is supplied as display Mesh geometry.
