NTM Doors
NOTE. This mod is a WIP. More updates are planned.
HBM's doors, without the rest of the mod.
NTM Doors is a standalone Forge 1.12.2 port of the multiblock door system from HBM's Nuclear Tech Mod. No NTM installation is required — every model, texture and sound is bundled.
Current version: 1.0.24
16 multiblock doors
- Vault-Tec Blast Door — 5x5 rolling gear door
- Sliding Blast Door — 7x4 double-panel blast door
- Roller Blast Door — 1x7 roller shutter
- Secure Access Door — 5x5 rising security door
- Fire Door — 4x3 roller/fire door
- QE Sliding Door — 2x2 double panel
- QE Sliding Door, 1x2 Column — single-column version
- QE Containment Door — 3x3 rising shield
- Sliding Seal Door — 1x2 pocket door
- Round Airlock Door — 4x4 split iris
- Cargo Door — 3x3 two-stage lift
- Large Vehicle Door — 7x6 split vehicle door
- Water Door — 3x3 swinging watertight door
- Silo Hatch — 5x5 tilting hatch
- Large Silo Hatch — 7x7 tilting hatch
- Transition Seal — huge keyframed 24-second sequence
Every door:
- places in one click, faces the player, and is removed as a single structure
- animates every moving part with the original HBM timings and sounds
- has state-dependent collision and selection boxes — walk through when open, click-through gaps
- responds to redstone from any cell (edge-triggered) and right-click
- is also registered as a redstone-only

Keypad
A wall-mounted code panel that binds to the door it touches:
- 1–6 digit codes, physical buttons, LCD prompts, leading zeros preserved
- a second keypad on the same door shares its code; placing one next to an already-bound door auto-syncs and shows purple
Code synced - the binding stays on the door if the keypad is broken, until the door itself is destroyed
Rcloses an open door when the pad's code matches the door- screwdriver reset: confirm, enter the current code, and the door plus all linked pads are cleared
- sneak + screwdriver cycles binding modes while the pad is unused:
- Distance — link one closed door within 32 blocks
- Multi — link up to 9 doors, adjacent or remote, all on one shared code
- after linking,
Confirm Door Bounding?is shown andEaccepts; the pad then showsInput code/Input multi code - once a pad has a code or any link, its mode is locked and the screwdriver can only reset it
Screwdriver + sneak + right-click cycles door skins:

- Secure Access — nine: red, yellow, green, blue, grey, black with white text, HBM yellow, white with black text, orange with white text
