vertShader:string = `
// https://github.com/pixijs/pixi.js/issues/6436 * this one!!!
attribute vec2 aVertexPosition;
attribute vec2 aTextureCoord;
uniform mat3 projectionMatrix;
varying vec2 vTextureCoord;
void main(void)
gl_Position = vec4((projectionMatrix * vec3(aVertexPosition, 1.0)).xy, 1.0, 1.0);
vTextureCoord = aTextureCoord;
fragShader:string = `
varying vec2 vTextureCoord;
uniform sampler2D uSampler;
uniform sampler2D u_lut;
void main(void)
vec4 pixelColor = texture2D(uSampler, vTextureCoord);
gl_FragColor = texture2D(u_lut, vec2(pixelColor.r, 0.0));
const filter = new PIXI.Filter(this.vertShader, this.fragShader, this.uniforms);
container.filters = [filter];
