Modular Underground Tunnels for Unity Low-poly 3D model

Modular Underground Tunnels for creating an underground environment on Unity. The scene is assembled from fully modular tunnel segments. With these modules, you can create underground tunnels, corridors and rooms, for example for the subway, large underground bunkers, underground drainage systems and much more.

A large number of props for filling underground spaces inside tunnels. Warehouse props, various destroyed debris, a lot of lamps for lighting, facilities for electrifying dungeons and more.

The scene features several types of vehicles as props: Railroad Trolley and Railroad Platform for big tunnels and a Battery Electric Locomotive, platforms and tanks for it, for small tunnels.

Features:

• Hight Quality Model & PBR Materials
• LowPoly - Game Ready
• Vertex Paint: Many architectural meshes support Vertex Paint. There are 4 channels available in vertex paint materials: destroyed concrete, moss/mold, puddle and puddle on destroyed concrete.
• Meshes have detail lods. Together with the configured occlusion colliders, they improve performance in the scene.
• Optimized the density of the textures. The density of unwrapped meshes is ≈ 1024 px/m2, and for small meshes the parameter may be noticeably higher.
• Different material options for most meshes (colored, rusty, old, mossy).
• PBR Materials. Maps Occlusion, Roughness, Metallic are collected in ORM packages.
• The signs with inscriptions have two spelling variants: Russian and English. You can switch by replacing the material or prefab.
• RTX lighting effects are included in post processes, for example Global illumination, AO, Reflection. You can disable them to save PC resources.
• The screenshots were taken in Unity 6 with RTX effects enabled.
• The main scene shows the possibilities of the package, and it itself is not designed to accommodate the characters due to the density of filling with objects. For your game, you may need to adjust the scene and the collision in it so that the character can run freely. If you bought this product, I allow you to use a scene from this product at your discretion, even in its entirety without making changes to it.
• Reused Textures for less stress on memory
• Reasonable poly count.

Product Parts

• The archive is divided into parts, since CGTrader limits the size of one uploaded file (5.5 GB). The split archive can be unpacked using the 7Zip archiver, it can be downloaded on the official website, or you already have it in your system.
• The product is divided into 3 parts due to the 6 GB file size limit for Unity file, but there is twice as much content in my product, so it is divided into parts.. Most of the textures in the main file are 2048x2048.
• To install high-resolution textures - 4096x4096, you need to download two additional files, unpack them and install them in your unity project with file replacement on top of the main product.

Unity version support

• The product has been tested on Unity 2022 and Unity 6, but it can also be installed on earlier versions with minor edits.
• A specially made version for Unity 6 should make your work with the product easier. Texture packs are made for version 2022 and can be imported into any other version without any problems.

Attention!

• To work with vertex colors, please install PolyBrush. It is located in: Package Manager / Unity Registry / PolyBrush
• All screenshots were taken in the HDRP version of the project in Unity 6. The engine settings files are included.
• A video flyby of the same work on a different engine - YouTube (The props, design and lighting are 99% correct, the textures and meshes are the same.)
• Watch the flyby of the overview map on YouTube. It was also made on a different engine, the only difference was that there were blooprints and particles on the stage, which are not present in the unity version.
