How would one add sunglasses or a backpack to a model, even change the shirt they wear.
Edit, maybe a code generator. A model is code generated into a node at complie time and a java file written, from that at compile time, one could establish the area that say the sunglasses are to be and then add them at run time ???.
The problem is not to add them accesoaries, but to add them at the proper place and keep it there on an animated model
