I am uploading my glb files to shopify and there is a problem with my export settings. as you can see in the image the lightening catches the materials/ sides of product differently and incorrect.

I am using blender and substance painter for my exports.

What is the cause of this ? It would be great If I don't have to re-do all materials for my models...  

Thank you in advance., help is very much appreciated.
