Triangular ripple on the surface

Questions
1

The application uses the gltf model, so it’s strange that on the local computer, when orbitally scrolling the model in space, the triangular edges are not displayed. But when we added light and uploaded it to the product server, a triangular ripple appeared on the surface of the figures. Is this because the light is not set up correctly?

You may need to adjust the .bias on the shadowmap to adjust it to the scale of your scene.

Also you want to make sure that the coverage of the shadowmap is tightly matched to your scene to maximize the precision you get from it.

Try like:


        light.shadow.bias = -.001;

or


        light.shadow.bias = .001;

and see if the symptom changes.
