Unity Terrain Paint Trees: How to Tutorial | LewyT Amusement Academy Part 5

Welcome back to the LewyT Amusement Academy! This is Part 5 of our series on building a theme park game in Unity. In this tutorial, we dive deep into the Unity Terrain Paint Trees feature, teaching you everything you need to know about populating your world with foliage and other 3D objects!

You'll learn the full workflow for adding trees to your terrain:
How to find and import free tree assets from the Unity Asset Store.
The essential step of fixing pink prefab materials by changing the shader to Universal Render Pipeline Simple Lit.
Mastering the brush settings, including size and density, to paint entire forests or dense obstacles.

We also cover critical techniques:
Tree Colliders: Testing trees in Play Mode to ensure they work as unpassable obstacles, like a dense maze.
Paint Trees vs. Dragging Prefabs: Understanding why painted trees are superior—they have random size variation and move dynamically when you raise or lower the terrain.

Advanced Terrain Building: Watch a speed-build of a volcanic island terrain for a slime game, utilizing multiple textures like sand, grass, snow, and lava rock.
