This is a lite edition of TerraTex, an automated script to texture Unity Terrains based on a wide range of configurable parameters.
Very easy to use, much less complicated than other tools with a user friendly interface and design

The lite version does not have all features but has enough for you to create simple textures as a base and for just trying out the tool before purchasing. For a full comparison of the lite and full edition, please see the table in the images section.

With this tool, you can create a wide range of terrain textures in seconds without manually painting them.

Check out the screenshots and videos to see what this tool can do with ease.
A demo scene is also included with an already generated texture that you can adjust the settings for to see the effect
