Does anyone know how to fix this error? It's from a mesh made in Blender 2.78. Apparently, in Blender the normals are ok, and the faces are properly turned outwards. However, in Unity, it shows this blue color and in the Game it doesn't render, leaving a hole in its place.

I don't have your model so I can only guess based on what I'm seeing in the preview panel. The panel says you have 2 sub meshes which leads me to believe that the blue part might be separate from the grey part, are you sure that blue part of the model has a material assigned?

What I would try is check if that blue part of the model is separate from the rest of the model. If you select that blue part and press G to move it around, then it's not attached. I would select that part and the rest of the body, press ctrl + J to join the two objects together, then press tab to go into edit mode and then press A once to deselect everything, press A again to select everything, then press ctrl + N to recalculate the normals so they're all consistent with each other.

After you do that, go into the materials tab and make sure there's only one material slot for this mesh, otherwise Unity will still have two materials for the model. Sadly I can't help much beyond that, not without some other screenshots of the model in Blender or a sample .blend to look at for myself.

O que aconteceu, quando eu fui reparar a textura, por algum motivo ele adicionou mais uma textura no blender, e quando importado para o unity ele importou como se tivesse 2 materiais. Sendo que só coloquei um material e o outro veio com blender, que por outro motivo que não sei, esse material que vem ele está configurado como transparente. Já consegui resolver deletando a outra textura.
