Five Japanese commercial buildings with window-view interiors, three LODs, Blender sources, and configurable room and sign lighting.URP 17.3.0 main package. Built-in: import main, then ALL matching Documentation alternatives in a separate Built-in project. Mac Unity 6000.3.5f2/Gamma tested. This mesh revision has not run on Windows; earlier checks cover Blender source display and Unity placement only. Other Unity/URP versions, Linear and HDRP untested.UNITY PREFAB GEOMETRYHigh preserves 100% of original triangles; Mid uses at most 70%, Low at most 50%. Already lower counts are retained. Percentages describe triangle counts, not image resolution or FPS. Static geometry is consolidated by material and spatial/floor region. Keep OptimizedLOD20261016 with the prefabs. Blender and FBX files are editable sources with their original LOD counts; source edits do not automatically rebuild consolidated meshes.INTERACTIVE DEMOOpen Assets/World3DWorks/Demos/Vol2/Vol2_START_HERE_Demo.unity, or Tools > World3DWorks > Demos. Press Play and open the Game tab. All included model prefabs are placed in this scene. On-screen controls provide an overview, per-model front/rear views, day/night, Automatic or fixed High/Mid/Low, and grouped light brightness. The demo starts with one model visible at Mid fixed; fixed modes ignore distance. The toolbar requires Unity's standard IMGUI module (com.unity.modules.imgui 1.0.0), enabled under Package Manager > Built-in. No Input System package is required. The overview uses at most 40 real lights per model (200 total); individual views light the selected model only. Demo point-light shadows are disabled. Original prefab settings and individual light ON/OFF data remain unchanged. For Built-in, import all matching Built-in alternatives in a separate Built-in project before opening the demo; these also install the demo scene linked to the Built-in prefabs.Five static buildings inspired by Japanese regional cities, Building 06-10, for PC streetscapes and background environments. Includes storefronts, local signage, window-visible interiors, rooftop equipment and three LOD levels.UNITY CONTROLSChoose Automatic, Fixed High, Fixed Mid or Fixed Low on each prefab root. Fixed modes ignore camera distance in Edit and Play. Master/category brightness multiplies individual light brightness and preserves individually disabled lamps. Interior, entrance and sign controls are included; use the product controls rather than editing a controlled Light Intensity directly. No user-written script is needed.INCLUDED AND SETUP5 LODReady prefabs, 15 FBX models, 15 editable Blender 5.0.1 files in Blender_source.zip, per-building demo scenes, lighting scripts and English setup documentation. Main content uses URP 17.3.0; configure URP before import/opening demos. Built-in alternatives are included in Documentation for a separate Built-in project. Text is editable in Blender; Unity and FBX use finished geometry text.LIMITATIONS AND CHECKSWindow-view interiors, not complete walkable interiors. No colliders, NavMesh or moving door/elevator animations. Materials use colour/metallic/smoothness/transparency values without standalone PBR texture maps. Dense geometry, many renderers and realtime lights can be demanding; choose detail/light/shadow settings for your hardware. No mobile/VR or FPS guarantee.Unity 6000.3.5f2, URP 17.3.0 and Built-in checked on macOS, including package import, fixed quality, grouped/individual lighting, saved scenes and actual Play. This consolidated-mesh revision has not been executed on Windows. Earlier user checks covered Blender source loading/display and Unity placement only.URP may reduce shadow-map resolution when many lights share an atlas; adjust shadow/light settings.Blender sources may embed Noto Sans CJK JP under SIL OFL 1.1; see Third-Party Notices.txt and the supplied font license. Unity Asset Store EULA applies.Vol.2 contains different buildings from Vol.1, including shops/offices and a ten-storey building with a bowling floor. Building10 has approximately 1.2 million triangles at High; this is a dense PC background pack.VERIFICATION SCOPEMac Unity 6000.3.5f2: Built-in and URP 17.3.0 imported, all LODs, fixed quality, grouped/individual lights, OFF-state retention, actual Play and camera renders checked.
