libgdx 3d FBX to g3db blender append

Problem: When i export a model that i've have appended something to in
blender to fbx format then convert it to g3db then run it in a libgdx
program the appended part of the model does not show.
Im not sure where the problem lies. Should be either Blender, the fbx to
g3db convertor or my program.
Doubt anyone will be able to answer this but thanks for any help.
