Hi,
After I made rigging of my character I decided to make some test animation. The idea was to make him picking up some objects. Well, I found that I don’t know how to make his skin collide with an object to make deformation looks neutral. And I don’t even have any ideas except using FLEX modifier. But, as I know Flex won’t allow me to make self-interaction. How can I make a character’s skin or muscles interact with any geometry and character’s body? Give me some suggestion, pleeeeeease 
Pardon my English 
Thanks
