Mesh Problems

I recently imported an arm into unity from blender as I have done many times with guns, it usually works fine but this time my arm dosent show up and theres an error in the console saying “SkinnedMeshRenderer requires a mesh with skinning information”. Im not to sure how to fix this but im hoping theres a way other than modelling a new arm, can anyone help me?

If you didn’t skin the mesh in blender, you need to use a mesh renderer, the basic one. Maybe there was a mix up during the import. If you did, the skin information isn’t found, so export and re-import again.
