Terrain Tools 3 Mixer
Mixer for Unity's Terrain Tools 3 is a free and Open Source extension for the Unity Terrain Tools version 3. You can stack and order the provided tools via drag & drop and change the size and opacity of the brushes quickly. During painting the tool stack is painted one after the other.
That way you can create an arbitrary order and use the tool as a road painter, path painter, river and lake bed painter, mountain andvances and so on.
This is an update to its predecessor Path Paint Tool which supports now Unity 2021+. The name got changed to "Mixer" because it'll become more over time with Unity's addition of more Terrain Tools like Terrace, Thermal and Hydraulic Erosion, Twist and even with their awesome filters for Noise.
Introduction
Let's see in a video how it looks like in action, please click on the picture to see the video on youtube. In the example I use the Mixer for creating a path from scratch for a bike driving scene:
Installation
In Unity 2020+ or 2021+ open package manager and install via git url:
https://github.com/Roland09/TerrainTools3Mixer.git?path=/Assets/TerrainTools/Mixer
Additionally you can download this free unity package which includes a Demo Terrain with Textures (see credits) in order to get you started quickly:

For older Unity versions I recommend Path Paint Tool.
Requirements
* Unity 2020+ and Unity 2021.1 ... support for Unity's experimental version of their terrain tools
* Unity 2021.2 ... support for Unity's release version of their terrain tools
Changes compared to Path Paint Tool
The code was adapted to work with Unity 2020+ and 2021+.
The UI has become more compact. The individual Terrain Tools are quickly accessible and the Brush Size and Opacity can be quickly compared and changed. To the right of the Terrain Tool Name is the slider for the brush size and next to it is the slider for the brush opacity, i. e. strength. Those values are relative to the overall Brush Size and Strength.

The Idea
Unity created and provided various tools for terrain manipulation for free. When I studied them I figured that it would make sense to combine them. So I tried and implemented a quick tool which combines various Terrain Tools in 1 paint stroke.
So the basic idea is to have multiple brushes overlapping, e. g.:
- inner brush: texture tool
- middle brush: path tool
- outer brush: smooth tool
Examples:
Multi-Tile Terrain Road & Path Painting
Vegetation Studio Pro Integration

Mountain Advancement
Resize / Rotate via keyboard shortcuts
Undo over Multi-Tile Terrain
Underlay Paint for e. g. River Beds
Notes
