It is Incorrect display when i use GLTFLoader

this is now loaded

this is what I want to achieve

I can do this with the following code, but the model is not quite right

There will be differences from those implemented in three.js Editor
Does anyone know what happened?

use child.material.emissive = child.material.color;

However, the rendered effect is quite different from the imported model in the three.js Editor. The following is a screenshot of the three.js edito

I hope the last few pictures will help you understand my question better

Do you mind sharing your glTF asset?
