Is your feature request related to a problem? Please describe.
When I set the receive shadow to true, when I move the scene, the stretched polygon in the scene will dynamically appear a black background on the side of the stretched polygon with its back to the sun.

@datouzhan , what lights do you have in the scene?

I set up AmbientLight and directionLight

There is another problem. I use lambert material on the top of the building, but unfortunately it doesn't appear in the color I set. Instead, it appears as black. I want to set the material to accept the light and let it change with the light.If I set the standard material, the top face will keep flickering as I move the scene.

when i use basic material on the top of the building, the color is normal

@datouzhan , sorry that I never responded. Somehow I lost track of this.

Have you made any progress?

I find it strange that you get this, we don't have such an issue on the shadow demo: https://www.harp.gl/docs/master/examples/#real-time-shadows.html

Have you done anything that could have affected it?
