Windy grass

just added the ability to add grass color (author’s shader https://godotshaders.com/shader/pixel-art-wind-sway-meshinstance3d-godot-4-0/)

Shader code
shader_type spatial;
render_mode cull_disabled, depth_draw_opaque;

uniform sampler2D grass_texture : filter_nearest, source_color;

uniform sampler2D gradient_texture : filter_linear_mipmap, source_color;
uniform float gradient_blend : hint_range(0, 1) = 0.5;

void vertex() {
    NORMAL = vec3(0.0, 1.0, 0.0);
    VERTEX.x += sin(NODE_POSITION_WORLD.x + TIME * 1.25 + UV.y) * (1.0 - UV.y) * 0.2;
    VERTEX.z += cos(NODE_POSITION_WORLD.z + TIME * 0.45 + UV.y) * (1.0 - UV.y) * 0.15;
}

void fragment() {
    vec4 grass_sample = texture(grass_texture, UV);
    vec3 base_color = grass_sample.rgb;
    float alpha = grass_sample.a;

    vec3 gradient_color = texture(gradient_texture, vec2(UV.y, 0.5)).rgb;

    vec3 final_color = mix(base_color, base_color * gradient_color, gradient_blend);

    ALBEDO = final_color;
    ALPHA = alpha;
}
