Your model seems fine to me:

This is how I load my models myNode = (Node)assetManager.loadModel(ā€œModels/myModel.j3oā€);
If you converted the model to .j3o correctly you donā€™t have to set the material. Itā€™s already set on the .j3o. Also, ā€œTangentBinormalGenerator.generate(geom);ā€ is not needed for this.

Also try triangulate your mesh before you export. Mesh->Faces->Triangulate Faces. Or just in edit mode with all faces selected press CTRL+ t.
