Make sure the faces are oriented in the correct direction and check if you marked some edges as sharp.
For the face orientation go into the Edit Mode, select the object, then hit “Shift + N”, which will recalculate the normals
For the sharp edges go into edit mode, edge select and look if you see any edges that are marked blue

And if you imported the mesh check if the normal data is baked
