Simple and customizable triplanar terrain shader with automatic top, side, and bottom blending for Unity’s Built-in Render Pipeline.This is a lightweight and easy-to-use triplanar terrain shader for Unity’s Built-in Render Pipeline that automatically blends between three textures: top, side, and bottom, based on the surface’s world-space orientation.It uses a true triplanar projection method to prevent texture stretching and provides independent controls for blend position and smoothness of the top and bottom layers, allowing for natural transitions between materials like snow, rock, and soil.The shader requires no UV mapping, making it ideal for stylized or semi-realistic terrains, cliffs, and mountain meshes.Its structure is clean and modular, allowing easy customization, extension, and integration into other Built-in shaders or custom systems.Render Pipeline Compatibility:Built-in Render PipelineTested with Unity 2020.3+, 2021.3+, and 2022.3+Features:True triplanar projection (no UVs required)Automatic blending between top, side, and bottom textures based on surface orientationIndependent control over blend position and smoothness for top and bottom layersAdjustable tiling and scale for each textureNo texture stretching thanks to real triplanar blendingLightweight, efficient, and suitable for stylized or semi-realistic terrainsIncluded Assets:Triplanar Shader (Built-in version)Example material presetSample scene with a simple terrain meshCustomization:Easily extendable (add more texture layers like rock, dirt, moss, etc.)Parameters exposed for intuitive material editingClean, modular, and well-commented shader code for easy modification and integration
