Question from GitHub: Cesium Model is very dark

When I view the model in cesium,the scene is very dark in some point of view ,and I try to set globe Light,but it’s useless.Whenever it’s day or night,the scene is not light.
viewer.scene.globe.enableLighting = true;
How can I make my scene become bright always in any point of view?

Setting viewer.scene.globe.enableLighting = true will enable the sun as a light source. Setting it to `false’ will enable both sides of the globe to always be visible. Another than than, we’ll need more information, probably a code example.
