Weird lighting issue after importing auto-rig

I am having issues with my character model looking weird after using Mixamo auto-rig



on the left is how it should look, on the right is how it looks AFTER using the auto-rig and then importing

How do i fix this?

Thanks for any help!

 

I noticed that if I replace the skinned mesh renderer with normal mesh renderer, its fixed but then the rig is "broken"

Still don't know how to fix the lighting issue so any help is appreciated!

 

I figured it out!!!

In blender, before exporting as fbx, apply all transforms by doing ctrl+a then selecting apply all transforms!
