URPShader

This asset provides a texture based solution for interactive grass.

It has unlimited customization using any 2D texture you like to render, adjustable colour with gradient settings, colour noise, wind noise with 2 blend modes, characters and mouse interactive behaviour.

Note: This asset is intended for top-down games, with a limited view, and might not be as performant with a bigger field of grass and thousands of individual grass blades, like in a 1st person game.
