Parcel Depot and Sorting Hall
Walk a working parcel depot: a belt line under a scanner arch, weigh and label stations, diverters dropping into sorting chutes, cages and pallets down the aisles, and two dock bays with vans and a lorry trailer.
About
What is placed
A sorting hall about 16 by 20 metres, laid on the pack's own floor and walkway tiles and closed in with wall modules. The belt line runs the length of it: an incline feed, powered straights, a scanner arch, a weigh and dimension station, two diverter arms and a curve into the gravity rollers. Sorting chutes, bag frames and post bags line the east side, with parcel cages, roll cages, tray racks, pallets and parcel stacks filling the aisles. Two roller shutter doors open onto a dock with leveller plates, bumpers, a shelter frame and bay signs, a delivery van at each bay and a box lorry trailer out in the yard. A mezzanine deck carries the supervisor desk over the north end, and the east side holds the check in counter, lockers, canteen run, vending machine and first aid point.
What moves
Conveyor rollers spin on the powered, incline, gravity and diverter sections, and the diverter arm swings across the belt. The label applicator tilts. The delivery vans open their side and rear doors, the lorry trailer opens, the forklift raises its forks and lifts its hood, and wheels roll on the vans, the roll cages, the pallet trucks and the forklift. The roller shutter, the locker bank and the vending machine open and close, and the wall extractor fans spin.
What does not move, and why
The belt surfaces themselves do not run. Every clip in this library is a rigid node transform, so a looping belt is out of reach, and so are straps, cables and chains. There are no staff and no drivers, because nothing here is skinned. Every livery is invented: no real courier company or van manufacturer is named anywhere in the pack.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
The sorting line
Parcels ride the powered belt under the scanner arch, which reads every label as it passes. Rollers turn on the powered, incline and gravity sections alike.
Parcel scanner arch over a belt (Parcel Depot and Sorting Hall)Weigh, measure, label
The weigh and dimension station prices each parcel by size and mass. The applicator beside it prints the routing label and tilts to slap it on.
Weigh and dimension station (Parcel Depot and Sorting Hall)Diverters and chutes
Two diverter arms push parcels off the belt into the sorting chutes, which drop them into the bag frames and post bags waiting underneath.
Diverter arm conveyor unit (Parcel Depot and Sorting Hall)Cages and stacks
Sorted work is built into parcel cages and roll cages here, with tray racks, pallets and stacks of boxes filling the aisle between rounds.
Parcel cage, loaded (Parcel Depot and Sorting Hall)The loading dock
Two bays with leveller plates, bumpers and a shelter frame. A van stands in the near bay with its doors open, and a box lorry trailer waits out in the yard.
