Cell block

Walk a 20 by 14 metre cell block built from the Prison Complex Builder pack: six barred cells with bunks, a mezzanine walkway and stair, a canteen with bolted tables, a kitchen and serving counter, the control desk and guard booth.

About

One block from 24 of the pack's 127 models, in the hall preset with concrete walls, cool light and light banks under a 7 m ceiling.

You come in through the block door past the intercom post and the restricted access sign. Six cells line the back wall, each with two bar wall panels and a barred door, concrete partitions, a bunk, a toilet-sink combo and a shelf; a mezzanine walkway with rails runs along the cell front, reached by the cell block stair. Four bolted canteen tables fill the middle, the kitchen run, serving counter and food trolley take the west side with the phone bank, and the control room desk, monitor bank and guard booth the east, with CCTV cameras watching from the walls.

This pack ships animation clips: the cell doors, the block door, the serving counter, the kitchen run and the food trolley play as you come within three metres and rewind when you leave.

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.

The cells
Six 3 m cells along the back wall: bar walls and a barred door in front, concrete wall segments between, and a bunk, a toilet-sink combo and a shelf inside each. The doors have clips and open as you approach.

Up to the walkway
The cell block stair climbs to a mezzanine walkway with rails along the cell front at 3.1 m. Walking stays on the floor; the walkway is scenery.
