Skinned Mesh material issue

Hello, hope you are having a great day!

I loaded an object file (glb), but it looks strange.

Could you anyone help me please?
Thank you in advance.

My guess is the normals are backwards for the face

@anidivr thank you for your answer.
So is it the problem with the model file? How can I fix it in Three.js?

Its usually a problem with the model file. To confirm, try the following to recompute the normals. If this doesn’t help, it must be something else.


I tried but the same issue.

I fixed this issue by creating a new material using its current texture.

gltf.scene.traverse((child) => {
        if (child.isMesh) {
          child.material = new THREE.MeshPhongMaterial({

But still don’t understand what was wrong with its original material.
