Hello!
I've done an addition to OBJ 2 JME converter to support 3D Studio Max generated files.
It only exports groups of objects and this cause the current converter to name nodes as temp1, temp2, and so on…
So I've managed to name generated object like the group in which they are defined if the object name is missing.
Here follows the patch:
