WW2 & Cold War Modular Military Bunker Entrance, Tunnel and Checkpoint

The pack includes an exterior mountainside entrance, checkpoint assets, a main bunker tunnel, smaller side corridors, bunker doors, defensive obstacles, lighting, pipes, cables, terrain elements, signage, decals and supporting props. The assets can be used to create clean operational sites, aged installations, or heavily weathered and abandoned environments. Please note: The assets included in the WW2 & Cold War Military Checkpoint Kit are already included in this complete bunker environment pack. The standalone Checkpoint Kit is intended as a smaller, lower-cost option for users who only need the exterior checkpoint assets and is available here: https://u3d.as/48YC The demo scene includes a fortified checkpoint set into a rocky mountainside, a two-section main tunnel, and two smaller side corridors. Key Features - Supports all pipelines: URP, HDRP and Builtin. - Fully modular tunnel and side-corridor systems, allowing both areas to be assembled in a wide range of lengths, layouts and combinations. - Modular bunker frontage with interchangeable tunnel entrances, wall sections and side-door configurations. - Modular mountainside and cliff pieces designed to blend the bunker frontage into a variety of surrounding terrain (terrain or meshes). - Faction-neutral visual design suitable for World War 2, Cold War, German, Soviet, Allied and fictional military environments. - English, German and Russian text decals included. By default text decal prefabs use the English texture. - Doors, gates and barriers use practical pivots designed for straightforward opening, rotation and animation. - Fully modular pipe and cable kits with practical pivots and scalable sections. Straight pieces can be scaled non-uniformly without visibly degrading the design. - Architecture assets use multiple material slots where appropriate, allowing walls and other structural pieces to be recoloured or customised independently. - Emissive materials and texture masks allow illuminated elements to be tinted, dimmed or disabled, creating multiple visual variants from the same asset. - High-quality, hand-authored textures and materials with detailed concrete, painted metal, wood, terrain, dirt and weathering treatments. - All applicable meshes include optimised LODs and collision for use in real-time environments. - Lens-flare card effects are included for additional atmospheric lighting and cinematic presentation (which can also be tinted). - Vertex animated grass meshes for terrain detail painting and manual set dressing. For a German themed guard hut please see: https://u3d.as/497T Requirements The animated grass material, the camera-facing lens flare cards and some of the projected decals use Shader Graph. The required package will be installed automatically on import. This is standard for URP and HDRP, and ensures compatibility with the Built-in Render Pipeline as well.
