i don't know if this topic fits in here but how do u make the keyframes all stretchy?
like the head goes big or stretches arms
and what program that can do that?
For that you need to make them from scratch, on max.
how do i get max yo?
you have to purchase it from 3DS or ebay. It costs roughly £1000, maybe a bit less if you buy an older version second hand.
I wouldn't recommend it, it has a very steep learning curve thus explaining the reduced number of meshers compared to skinners. To get the most of out max you need to go on a course.
