Non-Destructive Spline-Based Terrain Editor For Unity

TerraSplines by GRUELSCUM is a simple yet powerful terrain editing tool for Unity that lets you tweak terrains without permanently altering original data. It's perfect for creating stylized, cartoony landscapes or rapid prototyping, since it allows you to change anything at any time.

Getting started is easy: create your terrain and splines, parent them to an empty GameObject, and press the Find Refs button. TerraSplines works seamlessly across multiple terrain objects at once and offers Height, Paint, Hole, and Fill operations with configurable brushes, both global and local.

TerraSplines requires Unity 2022.3 or newer. The tool is actively maintained, with the latest 1.2.0 update released just a few days ago.
