GrassPaint is a geometry nodes-based asset library for generating and animating stylized grass in Blender. It is designed to work efficiently with the EEVEE render engine, though it functions in Cycles as well.

The system includes multiple operation modes, allowing users to distribute grass using a paint mode, apply noise-based variation, and mix different grass assets. It features built-in animation controls for wind effects, step motion, and an attract mode for interactive element responses. GrassPaint provides a selection of presets and customizable parameters to adjust the appearance and behavior of the grass elements.
