Linus Rosenqvist shows a simple setup to animate grass using noise and CHOPs rather than a Vellum simulation.

This new tutorial from Linus Rosenqvist forgoes the typical Vellum simulation in Houdini. It uses a simple CHOPs setup to animate grass blowing in the wind.

The setup is excellent for quick animation for any grass or fur in Houdini using noise and processing it with CHOPs.

While there are plenty of grass-building tutorials, few cover animation, and fewer still efficient animations without simulation.
