I made these pages to document how each setting in the new Terragen 2 program works. If you have any questions or comments, feel free to email me on: ryan AT motionmagnetic DOT com.

These pages is as basic as it gets, and is purely to provide visual reference to what each setting does when changed on it's own.

Note: You can find my other pages here:
Atmosphere Settings
Quality Settings

The first image of each row is a 'low' value of that particular setting, the second one is always the same, as it's the default settings, while the last image is a 'high' value.

Each thumbnail is linked to a larger version of the image.
