A very good engine! Now, being a complete novice, can anyone help answer the following queries? These are in connection with attempting to implement soft body physics and rag dolls on a character model (e.g. its skin gets depressed if pressure is applied)

1.
Cal3d appears to be the only character model file format that Sylphis can import. Is there a way to import high quality Poser models?

2.
Once a character model is imported, is it possible to program code to traverse the model vertices? Does this have to be done in Python or can I use C++?

3.
How would I access the bones and traverse the bone hierachy of a character? Also, how to rotate a given bone in software (Python or C++)

4.
How can facial expressions be modelled?

Thanx!
