Is there any known way so that, for example, if you make a character with his back against a wall, why not, when "pushing" it towards the wall, the lil guy will naturally stop when he its the wall? Or if you put a kid on an adult's shoulders, when you push the kid down his mom's shoulders will "stop" him from going through her body ? that's some collision issue too :) I am totally new to the whole concept of collision in Poser, this is why I ask.
