Interactive Grass

This shader allows objects to interact with the player’s movement, meaning they react dynamically when the player passes by. You can adjust the interaction range, movement, and even add noise-based motion if desired. This shader was originally made for Unity 6, but it also works quite well on Unity 2022 versions. It’s designed for the URP render pipeline with Shader Graph, and you can adjust the following:

• Texture, Color, and UV properties (Tiling and Offset)

• PBR properties with the PBR material.

• Alpha Clipping

• Movement SpreadNoise

• Movement Scale (useful for grass or other moving objects)

• Wind Speed

• Smash Amount (how much the interactive object is pushed when it collides with the player)

• Interactive Radius

• Noise Scale when pushed

• Wind Speed when pushed

If you plan to use this for grass or a large number of objects, I recommend marking those objects as “static” for better performance.T

his package includes an unlit material (useful for large amounts of objects like grass) and a PBR material for more detailed objects.
