Hey @chen21439 thanks for the question.

We have a couple sandcastle examples using custom post processing stages, I think this one shows how to pass uniforms like you’re looking for? Please take a look and let me know if that helps

      const noise = await Cesium.Resource.fetchImage({
        url: "/static/texture2.png",
      });
      new Cesium.PostProcessStage({
          fragmentShader: fragmentShaderSource,
          uniforms: {
            texture:()=>noise ,
          },
        })
