Sofy body dynamics on skeletal characters

Hi all,

I am new to the SIO2 engine (but work in the games industry) and was wondering if its fairly straight forward to isolate / affect a region of a character to do soft body dynamics? An example would be the fringe or long hair.

Also, what sort of vertex count would be the limit to apply soft body dynamics to without taking too much of a frame rate hit?

Any insight into this would be much appreciated.

Cheers,
