TerraSplines is a Non-Destructive Spline-Based Terrain Editor. Sculpt landscapes, create paths, fill areas, paint textures, and cut holes using spline-based workflows.URP is required for ShaderGraph shaders in the samples, but you can easily convert themDOCUMENTATIONDISCORDA simple yet powerful terrain editing tool that lets you modify Unity terrains without permanently altering your original data. Perfect for creating stylized, cartoony landscapes or rapid prototyping—change anything at any time without commitment or hassle. ALL SPLINE BASED!Easy Setup – Create your terrain and splines, parent them to an empty GameObject, then press the "Find Refs" button - you're ready to go!Key FeaturesNon-Destructive Workflow - Experiment freely and iterate quickly without permanently modifying your terrainMulti-Terrain Support - Work seamlessly across multiple terrain objects simultaneously (real-time updates may slow down linearly with the number of active terrains in your scene)Supports Multiple Terrain Operations - Height, Paint, Hole, Fill, with configurable brushes both global and local.Mixed Workflow - Combine workflows of TerraSplines + Unity Terrain Editor (EXPERIMENTAL)!!!
