Abandoned mine with PBR materials, made in Blender for the cycles renderer. It comes with 21 modular sections that you can use to assemble a mine, 19 accessories and several variations of some of the assets. 

Comes with diffuse, roughness, normal and emission maps, all in 4k. And the objects can be sub-divided if you need more polygons or used as they are, in case you have a low polygon budget.

This modular mine shaft is ideal for period pieces, horror projects or game scenes.
