Four metre tile split by an eruptive fissure: two shoulders of spatter welded ground either side of a 0.9 m gap that drops into a glowing crack, with the walls of the crack modelled down to the glow. Free 3D model for volcanic terrain, lava field and natural disaster game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 4.00 by 0.59 by 4.00 m (X by Y by Z). Metre units, +Y up, the front face toward +Z, resting on y=0 with the origin on the footprint. The fissure runs along Z through the middle of the tile, so modules chain into a rift of any length. Ports are on the left and right edges only, because the ends are open crack. Static geometry; no rig, collision or navigation data. Molten rock and glow seams are emissive geometry, never lights: the pack embeds no lights, and lava flow, steam, smoke and fire are static because a fluid needs a shader or a particle system that a rigid node transform cannot carry. A generic volcanic landscape: no real volcano, park, observatory or equipment maker is named or depicted, and every sign, plate and marker face is blank.
