Digger - Terrain caves overhangs
Digger is a simple yet powerful tool to dig caves and overhangs in your Unity terrains directly from the Unity editor. It gives Unity terrains the power of voxel terrains.
Games are increasingly incorporating overhangs and caves into their environments for heightened realism and diversity. Digger streamlines this process, eliminating the need for external tools, saving time, and reducing complexity.
This innovative tool allows you to seamlessly integrate caves and overhangs into your terrain directly within the scene view, all with a few simple clicks.
Digger is designed to give the impression of a voxel terrain without the associated drawbacks. It smartly maintains the reliable Unity terrain system, generating seamless cave and overhang meshes precisely where required. Under the hood, Digger employs voxels and Marching Cubes to construct meshes. Rather than entirely replacing the existing terrain with a voxel terrain, it blends the two, offering the best of both terrains.
With this tool, you will be able to:
➤ Dig in your Unity terrain just like if it was a smooth voxel terrain.
➤ Create overhangs (the opposite of digging).
➤ Apply different textures on the overhangs, in the caves, etc.
➤ With Digger PRO only: dig in real-time at runtime.
Key features:
➤ Easy to setup (see setup instructions) and easy to use
➤ 🔥 NEW: use your own mesh as a custom brush!
