Six and a half metre rope bridge across a fissure: a plank deck slung from two hand ropes between braced timber A frames, with the sag modelled into the deck and the ropes. Free 3D model for volcanic terrain, lava field and natural disaster game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 1.50 by 1.72 by 7.73 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 span runs along Z and the deck is at 0.9 m at the ends, dropping to 0.48 m at the middle; the A frames stand on the ground at either side. Static geometry; no rig, collision or navigation data. The sag is baked into the geometry and the bridge does not sway or bounce: a rope is a chain of soft bodies and there is no rigid node that can carry it. 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.
