ENDLESS TERRAIN
WITH THREE.JS & STEM STUDIO 3D GAME ENGINE
Create beautiful, infinite procedural worlds in minutes using STEM Studio's powerful Terrain object — no manual chunking required. Instead of building complex terrain systems from scratch, you can instantly generate massive, explorable environments that feel natural, dynamic, and endless, giving your players the freedom to explore without limits.

Why Endless Terrain Matters
In today's gaming world, players expect vast, explorable environments. Static, hand-crafted maps quickly feel small and repetitive. Endless procedural terrain solves this by generating infinite, unique landscapes on the fly — giving players the freedom to explore forever without hitting invisible walls.

Endless terrain is essential for:
- Open-world exploration games — Players can walk, fly, or drive for hours and always discover something new.
- Survival and sandbox games — Every playthrough feels fresh with different biomes, mountains, and valleys.
- Performance & scalability — Only generate what the player can see (streaming chunks), keeping your game smooth even on mobile.
- Replayability — Change a single seed number and you get an entirely new world.
STEM Studio’s Terrain object makes this incredibly easy. You no longer need to manually manage chunks, LOD systems, or complex noise layers — it handles everything automatically while delivering beautiful, natural-looking results right out of the box.

How to Set Up Endless Terrain in STEM Studio
1. Add the Terrain Object
In the STEM Studio editor:
- 1 Go to Library & Tools → Tools
- 2 Click on Terrain
- 3 One Terrain object is instantly added to your scene.
Note: Only one Terrain object is allowed per scene.
2. Main Terrain Settings (Right Panel)
Core Settings
- Enhanced Terrain — Enable for smoother, more natural looking hills
- Max Height — Overall elevation strength (recommended: 150–300)
- Seed — Change this number to generate completely new terrain
- Tree / Rock Density — Control how many objects are scattered
Water & Texture Layers
- Water — Enable realistic water plane
- Grass Max Height — Where grass transitions to rock
- Rock Max Height — Where rock transitions to snow
- UV Scale — Controls texture tiling quality
3. Adding Trees, Rocks & Plants
STEM Studio automatically scatters objects based on height zones:
- Plants appear in grass areas
- Trees grow in grass and lower rock zones
- Rocks appear in higher rock areas
You can replace default models with your own .glb files and adjust density and scale as needed.
Pro Tips for Best Performance
- Use lower tree/rock density on mobile devices
- Enable GPU optimization when available
- Experiment with different seeds to create unique biomes
- Combine with STEM Studio’s Fly or Over-the-Shoulder controller for instant exploration
