In order to prevent CPU spikes caused by new grass patches, ATG is a grass rendering solution that replaces Unity's terrain engine.

Beyond this initial goal, ATG provides notable enhancements in terms of lighting and wind motion.
Since version 1.2, ATG has been compatible with the Universal Rendering Pipeline, which enables touch bending and grass displacement. The High Definition Rendering Pipeline is now available (touch bending is not supported) as of version 1.34.
Version 1.07 of ATG allows you to employ its sophisticated lighting and bending features within third-party solutions, such as Vegetation Studio (BIRP only).
ATG is not an authoring tool; rather, it only renders your terrains using the grass and other elements you have included. Having said that, ATG works with any third-party authoring program that lets you make grass density maps for the pre-built terrains in the Unity editor, such as Terrain Composer. Currently, runtime distributed grass is not supported.
The most recent version requires Unity 2021.3 or later. However, a package for Unity 5.6.x and later is still available.
Note: You can use the files to test before you buy or for educational purposes. NOT FOR BUSINESS USE.
