Hytale Prefab Builder

Create reusable structures and buildings using Hytale's prefab system.

What Are Prefabs?

Prefabs are reusable structures that can be:

• Built once, placed many times

• Shared between worlds

• Used in world generation

• Exported and imported

Prefab Workflow

Step 1: Create a Prefab Editing World

/editprefab new <world-name>

This creates a dedicated world for building prefabs with special tools.

Step 2: Build Your Structure

Build your structure using normal building tools:

• Place blocks

• Add decorations

• Include entities (NPCs, furniture)

• Set lighting

Step 3: Select the Area

Use the Selection Tool to define the prefab bounds:

• Equip the Selection Tool (from Creative menu)

• Left-click to set first corner

• Right-click to set second corner

• The selected area is highlighted

Step 4: Save the Prefab

/prefab save <prefab-name>

Prefab is saved to: %APPDATA%/Hytale/UserData/Prefabs/

Step 5: Exit Editing World

/editprefab exit

Placing Prefabs

Method 1: Paste Brush

• Open Creative menu

• Select Paste Brush

• Choose prefab from list

• Click to place in world

Method 2: Command

/prefab list # Show available prefabs /prefab paste <prefab-name> # Paste at current location /prefab paste <name> <x> <y> <z> # Paste at coordinates

Prefab Best Practices

Structure Design

• Start with floor - Build from bottom up

• Include margins - Leave space around edges

• Consider rotation - Design to look good from all angles

• Add variation points - Mark where randomization can occur

Naming Conventions

Use clear, descriptive names:

building_house_small building_house_large dungeon_entrance dungeon_room_treasure village_market_stall decoration_fountain

Organization

Group prefabs by category:

Prefabs/ ├── buildings/ │ ├── houses/ │ └── shops/ ├── dungeons/ │ ├── rooms/ │ └── corridors/ ├── decorations/ └── nature/

Advanced Features

Prefab with Entities

Prefabs can include:

• NPCs (villagers, merchants)

• Creatures (pets, guards)

• Items (chests with loot)

• Interactive blocks (doors, switches)

Prefab Variants

Create variations of the same structure:

• house_wooden_01 , house_wooden_02

• Same base design, different details

Nested Prefabs

Use prefabs inside other prefabs:

• Place sub-prefab

• Build around it

• Save combined structure

World Generation Integration

Prefabs can be used in procedural world generation:

• Create prefab structures

• Define placement rules (in Pack JSON)

• Game spawns prefabs during world gen

Example placement config (in Pack):

{ "type": "prefab_placement", "prefab": "building_house_small", "biomes": ["plains", "forest"], "frequency": 0.1, "minSpacing": 50 }

Troubleshooting

Issue Solution

Prefab not saving Check selection is valid

Missing blocks Ensure all blocks are in selection

Entities not included Verify entities are within bounds

Prefab invisible Check file location and permissions
