const vec3 weight = vec3(0.2126, 0.7152, 0.0722); vec3 Grayscale(in vec3 o, float value){ float lumin = dot(o, weight); vec3 final = mix(o, vec3(lumin), value); return final; } vec4 frag() { vec4 pixel = texture(mainTexture, v_uv); pixel.rgb = Grayscale(pixel.rgb, intensity); return pixel; } 2. I tested it with an image.
