A complete modular military bunker environment for building fortified checkpoints, underground facilities and historical military locations.

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.

The demo scene includes a fortified checkpoint set into a rocky mountainside, a two-section main tunnel, and two smaller side corridors. The bunker entrance is integrated into the surrounding landscape using a Landscape Visibility Mask, with the exposed terrain edges concealed and blended using the modular cliff kit.

Key Features

• 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 (landscape 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. Language sets can be changed by selecting the text_decal actors and assigning the relevant material, or by replacing the base-colour texture within the decal material.

• 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 (ranging from simple Unreal generated to handmade) for use in real-time environments.

• Lens-flare card effects are included for additional atmospheric lighting and cinematic presentation (which can also be tinted).

The included demo scene uses Unreal Engine’s HDRI Backdrop plugin for the sky and ambient environment lighting. The plugin should be enabled to reproduce the demo scene lighting as shown.

Note for 4.27: All lighting is real-time and will look slightly different from the Lumen enabled 5.0+ version.
