About
Original CC0 cave construction kit with thick interior shells. Standard tunnels occupy a 4 m grid, 2.9 m clear width and 3 m headroom. Squeeze, gallery, chamber and shaft connectors carry distinct profiles. Cutaway assets and assembled examples make interiors reviewable.
Files load directly from the CDN. Choose the pieces you need. Colliders, navigation and gameplay scripts are supplied by your game.
