^^^^^^^^^
I think this is where the problem is: the prototype of getName is
const Char8 *getName(AttachmentContainerPtrConstArg container);
It returns a C string, i.e. a pointer to a character array, which you
can not compare with ==. You either need to use the strcmp function or
create a temporary std::string like this:
if(std::string(getName(scene)) == "Gelenk")
Hope it helps,
Carsten
