HELP! Copies of a body dont get imported with material from Blender

I have a model in Blender that I would like to export to Unity. In Blender, all of the bodies have their own texture. Some bodies are copies of another body. When I Export the FBX model from blender I use the copy mode.

The problem that I have is that when I import the fbx model that I generated in Blender into Unity, the copies of the different bodies dont get their texture. I upload two images to represent my problem.

In blender both of the bodies have the same texture and color, but in Unity, the copies dont have any material at all, it appears with no material. What can I do?
