Installation

Requirements

• Unity 2022.3 LTS or Unity 6
• Any render pipeline: URP 14 or newer, HDRP 14 or newer, or the Built-in Render Pipeline (Built-in needs the free Shader Graph package from the Package Manager)
• The Physics module (for colliders, Play Test and terrain tools)
• Input System package or the old Input Manager – Play Test works with either

Import the package

1. Open your project in Unity 2022.3 LTS or Unity 6.
2. Open the Package Manager (Window > Package Manager), select My Assets, find Procedural Cave Builder and click Download, then Import.
3. Keep the Arkerion Studios/Stylized Nature/Shared folder selected in the import dialog: the materials and the tool use it.
4. Using the Built-in Render Pipeline? Install the free Shader Graph package from the Package Manager.
