The problem with very dark models

CesiumJS

Hello, everybody!

I have a lot of models on Cesium,But their shades don’t look the same.

They look dark from certain angles:

I tried using DirectionalLight to solve this problem,

  viewer.scene.light = new DirectionalLight({
    direction : viewer.scene.camera.directionWC,
    intensity: 1.0,
  });
  viewer.scene.preRender.addEventListener(function () {
    (viewer.scene.light as DirectionalLight).direction = Cartesian3.clone(
      viewer.scene.camera.directionWC,
      (viewer.scene.light as DirectionalLight).direction
    );
  });

That still doesn’t solve the problem,So, I was wondering if there was a way to make my model always bright.

Unfortunately, DUE to confidentiality, I can’t provide sandcastle.

Thank you very much!
