About
A morning launch field, built round the one thing most balloon assets leave out: the envelope is supplied in every state a crew actually meets it in. There is a 17 m envelope fully inflated and standing on its mouth, the same envelope half full of cold air and leaning over between the fan and the first burn, 23 m of it walked out flat on the grass with its folds and seam tapes, and the stuff bag it packs into, with the crown line and side lines flaked out beside them. Under them go the wicker baskets in two sizes, the four person basket with its stainless uprights, load frame and twin gimballed burners, a spare burner unit, propane cylinders singly, strapped into a transport basket and racked six at a time, the fuel hose run, the petrol inflation fan and a spare guard cage, the inflation scoop, ground handling lines, a drop line, a crown rope coil and ballast bags. Getting the balloon there and home is the basket trolley, the recovery trailer loaded and empty, an unbadged recovery vehicle body and a roof rack. Running the launch is the windsock, a pilot balloon on its stand, marshal flags, pitch marker posts, tether anchors, a briefing board and blank faced flight instruments and radios. The event side adds crowd barrier and rope perimeter bays, bunting, a registration gazebo, trestle tables and folding chairs, a catering van with a lifting serving hatch, a first aid point, toilets, bins, a generator, floodlight masts, flag poles, finger posts, cones, a bunded fuel bay and an extinguisher stand. The field itself tiles from 8 m grass, mown lane and farm track modules with hedgerow bays, a five bar gate, hay and straw bales and tree clumps. Clips are rigid node transforms only: the burners tilt in their gimbals, the fan blades spin inside their static cage, cylinder valves turn, road and castor wheels roll, the field gate swings, bin and generator lids lift, the vehicle and catering hatches open and the trailer tailgate drops. Everything flexible is modelled at one attitude and stated static: envelope fabric, crown and side lines, ropes, hoses, bunting, flags, the burner flame and the windsock all need a joint per element, a deforming surface or a shader, and none of that is reachable with one rigid node transform. An inflating envelope is a cloth simulation, so it is supplied as separate posed states instead, which is what makes the pack usable rather than a single balloon nobody can stage. No people and no skinning anywhere. Nothing carries a real operator, festival, fuel company, vehicle marque, instrument or radio name: every envelope is a plain invented arrangement of gores and bands with no logo, wordmark, character, flag or shaped special and no registration marking, and every board, panel, hatch surround, flag and vehicle side is blank or wears an invented abstract shape. Original AI-generated CC0 geometry, prepared for human review. No physics, gameplay, colliders, navigation or embedded lights.
