Dear Land Former, 

Fins & Spines: Landform Terrain Brushes are designed and curated to provide dynamic brushes for easily producing raised ridges that resemble fins and spines in 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: 

Press and drag the brush directionally. A single brush stroke is sufficient to generate a fin or spine like landform. Motion, brush strength/opacity, strength jitter (Terrain Tools), and especially rotation all determine the outcome. For example, slowing the motion of a brush stroke/path will generate points of emphasis and contrast.

For visual examples and instructions please watch the preview video 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 and brush sizes ranging from 40 to 128. 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. Using the Terrain Tools preview package, it is recommended to add jitter to the brush strength, in the range of 0.1 to 0.4. 

Changing the rotation of the brush will change the results of the brush depending upon which way the brush is being directionally dragged. Some brushes can be telling of their potential directional 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 Land Former!
