Terrain: About

The Terrain Editor is where you shape the landscape of your world. You can define the biome type you want for your level, as well as the initial height of the hills. You can texture the terrain using up to 8 textures — and even blend each of these with 8 more! 🎨

But the terrain editor offers much more than just shaping and texturing:

• 🌲 Paint trees in an optimized way to create vast forests. Each tree is an instance of a source tree mesh for performance.
• 🌾 Paint grass with different types that can be mixed. Grass is rendered using simple 2D sprites that always face the camera.
• 🪨 Paint rocks, You can generate them dynamically or use the ones already generated. Like trees, they are instantiated from a rocky source mesh.
• 🛣️ Create paths — this feature is still under development but will be available soon.

Each part of the terrain editor will be explained in detail in the upcoming chapters. Here’s what the Terrain Editor looks like:

🧭 Editor Interface

The interface is composed of a 3D scene and a right-side control panel. In the top-right corner of the 3D scene, you’ll see a globe icon 🌐 — this opens the painting and sculpting tools, which activate a brush:

Clicking the globe opens the full toolbar:

Each tool performs a different action, which we’ll explore in the next chapters. Once you select a tool, a brush appears in the scene, showing its current radius. Here's how the brush looks:

🕹️ Brush & Camera Control

When a brush is active, camera movement is disabled so you can interact freely with the terrain. To move the camera again, you can either:

• Click the 🌐 globe icon again to close the toolbar
• Or hold down the spacebar and use the arrow keys (←↑→↓), or WASD (QWERTY) / ZQSD (AZERTY) to move.

But before using all these tools, you first need to generate a terrain. We’ll cover that in the next chapter. ⛰️
