meshes turn black after import

hello everyone. After importing the fbx file, some parts are black. I checked with the face orientation method in blender but there doesn’t seem to be a problem with the normals. how can i solve this problem.

Are the pillows and pillows bottom pillow linked instances collections by any chance (in blender)? If so try unlinking them and applying transforms.

Thank you! Um how do you do that? unlink them and apply transform?

To break the link use make single object


Then you can apply all

Then you can flip normals where needed (if it still comes in black in ue)
