Get Textures Active on a Terrain or Renderer by Simple Footstep System Example | Unity Tutorial

Learn by example! In this tutorial you will learn how to get the texture(s) active at a given point on a Renderer and a Terrain. We'll construct a primitive footstep system, Raycasting down from the center of a Character Controller and sampling which textures are active at that point. For the Renderer, it's relatively straightforward. However, Terrains are much more complex. We have to do some math to determine the Terrain position, then consider possibly multiple active textures because the Unity Terrain uses splatmaps to blend textures, allowing multiple textures to be active. 👨‍💻 As always, the full project from this video is available on GitHub: https://github.com/llamacademy/get-terrain-texture 🏷️Save 25% on the ultimate C# IDE: JetBrains Rider with code LLAMACADEMY: https://www.jetbrains.com/store/?section=personal&billing=yearly 📚 Resources ⚫ Footstep sounds I use in my games: https://assetstore.unity.com/packages/audio/sound-fx/foley/all-footsteps-sneaker-edition-89922?_aid=1101l9QvC ⚫ Terrain: https://docs.unity3d.com/ScriptReference/Terrain.html ⚫ Terrain Data: https://docs.unity3d.com/ScriptReference/TerrainData.html ⚫ Terrain Layers: https://docs.unity3d.com/ScriptReference/TerrainLayer.html ⚫ Material - https://docs.unity3d.com/ScriptReference/Material.html 🧡 Believe in LlamAcademy's mission and have received value from the videos?
