🚀 Why Use Terrain Builder?

Terrain Builder is a powerful tool that offers direct modification of terrain and object placement, which makes it essential for creating immersive environments in DayZ. Some of its key features are:

Feature	Description
Real-Time Visualization	Use the Bulldozer tool to visualize the changes you make as you shape the terrain or place objects.
Precise Object Placement	Place and adjust objects with precision. Unlike other tools, Terrain Builder lets you hard-code objects into the map, which can have performance benefits on server start-up.

📊 Terrain Builder vs. Editor Insights

There are often questions about what Terrain Builder can do that the DayZ Editor cannot. Here is a great insight shared by Duncan

Source: Discord Community Insight, a community member, regarding the advantages of Terrain Builder:

"When you place objects through Terrain Builder (TB), they get hard-coded into the map, making it easier and lighter on server start-up. With the Editor, objects are added as scripts that force the server to aggressively spawn all that stuff upon server start. This approach can be terrible for server performance in the long run, especially for complex game modes like Stalker, which involve numerous scripts and mods. Many server owners may prefer to avoid heavily scripted maps or may simply bake the objects themselves.

A good middle ground is to place objects in Editor first and then export them to TB, which provides flexibility and efficiency. Personally, I prefer Terrain Builder since you can adjust terrain in real time." - Duncan

This community insight highlights the practical benefits of using Terrain Builder, especially for server performance and creating well-optimized maps.

🔑 Key Points from Duncan's Insight:

• Hard-Coded Objects in TB: Objects placed through Terrain Builder are hard-coded, resulting in easier and lighter server start-up.
• Scripted Objects in Editor: Objects added via DayZ Editor are added as scripts, which can negatively affect server performance.
• Server Performance: Using Terrain Builder is more efficient for servers with complex game modes or heavy scripts.
• Balanced Approach: A practical solution is to start with DayZ Editor for initial object placement and then export to Terrain Builder for refinement.
• Real-Time Terrain Adjustment: Terrain Builder offers real-time terrain adjustments, making it a preferred choice for Duncan.

🏗️ Terrain Builder Project Setup Guide

This guide provides an overview of the recommended folder structure and essential files needed to set up a custom map in DayZ using Terrain Builder. It includes descriptions of each key folder and file, as well as step-by-step instructions for organizing and configuring your project.

🔧 Configuration Templates

In the config_templates folder, you’ll find essential configuration files that serve as starting points for your custom terrain project:

• layers.cfg: Maps colors in your mask file to specific textures. Adjust this file to match the textures and colors you are using in your project.
• config.cpp: Sets up primary terrain parameters like map size, grid details, and pathfinding settings. Customize paths and settings based on your project requirements.

How to Use

1. Copy Files: Copy layers.cfg and config.cpp from the config_templates folder into your project’s source or data folders as needed.
2. Modify Paths and Parameters: Update the file paths and any other parameters to fit the structure of your own project.

Refer to this documentation for additional guidance on configuring these files.

📁 Key Files in Terrain Builder Projects

When working with Terrain Builder, there are several important files that play a critical role in building and configuring your map:

1. layers.cfg: Defines how different textures and materials are applied to your terrain based on the mask image.
2. maplegend.png: Visual representation of color codes used in layers.cfg.
3. mask.png: An image file where different colors represent various terrain types, such as grass, roads, and water.
4. heightmap.asc:
   • ASCII grid file containing elevation data for your terrain.
   • Generated by one of the following tools: GQIS and L3DT
   • This file is critical as it forms the foundation for your 3D map by storing elevation information. Think of it as a 2D version of your terrain that defines the x, y (like in a math graph), and also includes the z (height) coordinates. For example, if you want to create a hill, the heightmap defines how steep or gradual the slope is, directly impacting how the physical terrain appears and interacts within the game environment. Think of this as a 2D version of your map that stores the x & y (like in a math graph) coordinates.
5. satmap.bmp: High-resolution satellite image used as the base texture for your terrain.
6. config.cpp: Configuration file defining various terrain parameters, such as map size, grid size, and object placements.

🚀 Setting Up Your Terrain Builder Project

Follow these steps to set up your Terrain Builder project for DayZ map creation:

1. Prepare Your Heightmap:

   • Create or obtain a heightmap.asc file that represents the elevation data for your terrain.
   • This file determines the physical shape and features of your landscape.

2. Design Your Mask:

   • Develop a mask.png where different colors correspond to various terrain types (e.g., green for grass, blue for water).
   • Ensure this aligns with the mappings in your layers.cfg and matches colors in maplegend.png.

3. Configure Layers:

   • Edit the layers.cfg to map colors in your mask to specific textures.
   • Ensure that the maplegend.png accurately represents these mappings.

4. Set Up Configurations:

   • Define your terrain's parameters in the config.cpp file, including map size, grid size, and other essential settings.

5. Organize Your Folders:

   • Place each file in its appropriate folder (source, data, navmesh, world) to maintain organization and ensure Terrain Builder can locate all necessary files.

6. Run Terrain Builder:

   • Open Terrain Builder and load your project files. Follow standard map-building practices, using the textures, elevation data, and objects specified in your folders.
