Build immersive, detailed underground environments with

Customizable Mine and Caves PBR 

–a comprehensive, production-ready modular kit designed for creating realistic mines, tunnels, quarries, and subterranean levels.

Featuring a snap-ready modular rail network, structural timber supports, working elevator shafts, interactive props, and rocky cave geometry, this pack gives you complete freedom to construct anything from tight abandoned mine shafts to massive industrial excavation sites.

KEY HIGHLIGHTS:

• Modular Rail System:

Complete set of straight tracks, slopes, gentle and tight curves (15°, 30°, 45°), and multi-way junctions to build intricate underground transit networks.

• Customizable Shader Controls & Biome Presets:

Powered by Shader Graph with instant material presets included 

(Desert, Winter/Snow, Mossy/Green, and Sci-Fi/Industrial).

• Ready-to-Use Combined Prefabs:

Pre-assembled corridors, intersections, slopes, and elevator shafts to block out and assemble playable levels in minutes.

• Interactive Props & Equipment:

Fully modular minecarts, mining elevators, hanging lanterns, tools (pickaxes, shovels), crates, chains, and structural braces.

• Fully Optimized:

Every modular piece includes 4 LOD levels (LOD0–LOD3) and custom collision meshes for smooth performance in any game genre.
