Note: if you buy Digger you can get Digger PRO for a lower price.

More and more AAA games add gentle overhangs and caves to their environment to make it more realistic, more interesting and more diversified.

A common way to do this is to create 3D models with an external modeling tool, and then place them manually over the terrain and blend them with it. This is tedious, unpractical and inefficient unless you have an army of 3D artists and level designers... and even in that case, you'd probably want them to focus on more valuable work.

This is where Digger comes to action. No more external tool required, no more loss of time, no more headache. It lets you create caves and overhangs on your terrain directly within the scene view, in a few clicks.

It will make you feel like you have a voxel terrain in your hands, without the downsides. It actually keeps the new, fast and reliable Unity's terrain system and creates seamless cave/overhangs meshes just where you need. Internally, Digger uses voxels and Marching Cubes to create meshes, but instead of replacing the entire terrain with a voxel terrain, it creates a mix of them and gives you the best of both worlds.

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 (as long as you read setup instructions)

➤ Dig/add mater on terrain

➤ Paint textures on cave meshes

➤ Paint/unpaint holes on cave meshes so you can integrate your own underground meshes

➤ Automatic collision solver

➤ Automatic LOD groups creation

➤ Multi-terrains support

➤ Full NavMesh support

➤ Compatible with any Unity terrain, whether it was made by hand, with Gaia, MapMagic, TerrainComposer or any other tool

➤ Only with Digger PRO: dig in real-time, at runtime.

➤ Only with Digger PRO: update NavMesh at runtime.

Shader support:

➤ Bonus: adds triplanar mapping to built-in terrain shaders

➤ Standard terrain shader

➤ URP terrain shader. For URP 10, 11, or more recent, you must import DiggerURP_10_11.unitypackage file manually after installation.

➤ HDRP terrain shader (only with Unity 2020.1+)

➤ MicroSplat (requires MicroSplat Digger module)

Other features:

➤ Full undo/redo support in editor

➤ Lets you set higher resolution for Digger generated meshes

➤ 'Sync & Refresh' button to recompute everything (useful if terrain textures or terrain heights changed)

➤ 'Clear' button to remove all modifications made with the tool

➤ Remove grass and details automatically

➤ Persists modifications on the fly

Requirements:

Digger requires Unity 2019.4 or a more recent version. It also requires Burst package.

Limitation:

➤ Doesn't work properly with terrain lightmapping
