There is no code for normal generation in the plugin, if you do not specify the normals for the mesh, they will be wrong. You need to specify either the vertex or face normals. The goal was to write an importer for VRML generated by 3DS Max and similar tools, not to implement the full VRML spec (which says that the browser should generate normals if they are not provided). However, feel free to contribute a patch if you need this functionality.
