Procedural Toolkit is a collection of instruments for creating procedural generation systems in Unity game engine. It is free, open source and does not require a Unity Pro license.

Warning: Be aware that this is a programming toolkit, editor support is limited.

Download toolkit from repository or Asset Store and place it somewhere in your Unity project (e.g. "Assets\ProceduralToolkit"). After that you can import ProceduralToolkit namespace in your script and start building your own PCG systems:

using UnityEngine;
using ProceduralToolkit;

public class Example : MonoBehaviour
{
    private void Awake()
    {
        Debug.Log(RandomE.fullName);
    }
}

Folder containing example classes and scenes (".\Examples") can be safely removed. The same is true for ".\Shaders", if you are not using examples. Removing ".\Editor" will leave you with code-only toolkit.

• RandomE: Random extensions for arrays, value generators.
• MeshE: Mesh extensions and constructors for primitives.
• MeshDraft: helper class for procedural mesh generation.
• TextureE: Texture extensions and constructors.
• ColorE: Color extensions, HTML colors.
• PTUtils: useful utility methods.
• Datasets: various data.

• ProceduralToolkitMenu: constructors for primitives and about window.
• MeshFilterExtension: Mesh saver.

Khrushchyovka: a procedural building generator
ChairGenerator: a procedural chair generator
Boids: a single-mesh particle system with birds-like behaviour
Breakout: a Breakout clone with procedurally generated levels
CellularAutomaton: a generic cellular automaton
Mazes: a maze generators
TerrainMesh: a simple terrain based on Perlin noise and coloured according to height
Primitives: a demonstration of primitives

Support is provided via GitHub issues and end email.

Keep in mind, that toolkit is developed and tested in second to last minor release of Unity. As of this writing, the latest version is 5.3, so you can expect toolkit to be working in 5.2. Actually, it should work fine even on 4.6, but you are on your own. Also, UnityScript interoperability is not tested.
