glTF model's shadow


I have a question of glTF model.

On this perspective,model is normal

But when I change perspective,Some places will darken,I want to remove this effect,what should I do?



One way would be adding some ambient color to your model. It looks like lighting is based on the camera rather than the sun, so if you are viewing a slanted surface it will appear dark.

Can you give me code example?

Actually can you send over the model, it will be easier for me to check that way.
