Does objToJme apply a default material when there is no defined?
In objToJme I read
/** Default material group for groups without a material */
I converted an obj with no mtl no materials to jme binary, and when I try to load the jme binary in headless mode it tries to load a material state.
If so it may cause problems in headless mode with physics models... ?
Importing on the fly with collada is ok
