How to Use Instant Building Mode and Structure Hotkeys

Building fortifications quickly during a survival encounter requires learning the mod's dedicated building mode and structure hotkeys. Instead of placing single blocks one at a time, you can snap full defensive pieces into place around you.

Entering Building Mode

1. Press Tab during gameplay to enter building mode. If you cannot see the building HUD on your screen, press O to toggle the building interface back on.

2. Hold the building pencil tool in your hand. Holding the pencil displays a visual placement preview in the world so you can see exactly where your next structure piece will land.

3. Right-click while holding the pencil tool to cycle through your available building materials.

Placing and Rotating Pieces

Once your material is selected and your preview is visible, use the dedicated hotkeys to place structures directly into the world:

• Press Z to place a wall.
• Press X to place a floor.
• Press C to place stairs (ramps).
• Press V to place a roof.

If a piece is facing the wrong direction in the visual preview, press R before placing it to rotate the selected structure. When the fight is over and you want to return to normal tool and weapon handling, press Tab again to leave building mode.
