Dear Mountain Mover, 

Dynamic Range: Mountain Terrain Brushes are designed and curated to provide dynamic brushes for easily producing mountain ranges with a single stroke. 

Brushes were specifically designed, curated, and tested for and through the 'Raise or Lower Terrain' use. They are compatible with terrain stamp use, along with every other type of brush use, found in the built-in Terrain Editor or Unity’s 'Terrain Tools' preview package extension. Deviating use types have not been tested. 

Brush Strokes: 

It is found and recommended to press and drag the brush directionally at a steady speed. This initial brush stroke can be sufficient to generate a mountain range. A back-and-forth stroke of the brush along the original stroke can provide more dynamic iterative results. Slowing the motion of a brush stroke can generate points of emphasis. For more dynamic results while directionally pressing the brush, move the brush up and down adjacent to the direction or making any motion while moving the brush along its desired range path. Mountain ranges can be iterative requiring several brush strokes.

For visual examples please watch the preview or example videos above.

Brush settings: 

In the default terrain editor, a brush opacity below 40 is recommended. While this brush set works in the default terrain editor, it is highly recommended to install the Unity preview package Terrain Tools, for optimal use. Using the Terrain Tools preview package, a brush strength of less than 0.2 is recommended. 

Recommended brush sizes ranging from 40 to 128. Using the Terrain Tools preview package, it is recommended to add jitter to the brush size and strength, in the range of 0.1 to 0.4. As the brush size increases or decreases incrementally adjust strength in correlation. A higher brush strength to size ratio will result in more unreal and dramatic terrain sculpting and brush stroke results. 

Creative Disclaimer: As a toolset, this brush set is designed with the intention to enable creative possibility. These recommendations in brush use and settings are suggestions to ensure tested and intended quality, not to hinder or limit your own creativity. Your preferences and experimentation are encouraged! 

Enjoy dear Mountain Mover!
