This tank is already in the library (previous.glb, previous_final.png, previous_side.png, build_t90-tank.py, previous_nodes.json; its baked textures are on gex44 in /root/fal-author/t90-tank-v2/textures: copy what you reuse into your own remote dir, never write in the old one). Games now need it DESTRUCTIBLE like the newer library tanks. Keep the model exactly: same shape, proportions, frame, origin, materials, texture look, node names, pivots, Paint material and factor, paints in nodes.json. Start from build_t90-tank.py and change only this: (1) every bolt-on item becomes its own Part_ node with a complete surface underneath (for this type: the Kontakt reactive armour blocks on the glacis and turret (grouped: one Part_ per row or panel of blocks), rubber side skirts with ERA panels (one per panel), the rear fuel drums, the recovery log, snorkel tube, stowage boxes, tow cables; turret: the Shtora dazzler boxes, smoke grenade launchers, roof machine gun station, sight heads, antennas); (2) the barrel is split from Gun into a child Barrel, the empty Muzzle becomes a child of Barrel at the tip with identity rotation (+Z forward); (3) add the Fx_ empties and the hatches the rig asks for; (4) build FILE B, the damage GLB, from copies of your meshes, with its Burnt and Scars textures; (5) render states.png and look at it. Everything else in the contract below holds.",
