Sorry about my english, but I’m spanish.
Ok… the pieces are:
If In the begining there is a person walking along and then he stop and look to other person doing something you can animate it continuosly. But then if you change your camera shoot like a first plane to the other person doing something you can animate that in other track (not other animation, just other track of animation). In some programs they call it “clips”.
For the animation just open the environment and import the character. If the environment it’s too big and in each animation you only see a part of the plane you can take just a piece and delete the rest of the geometry that we aren’t going to see. I don’t know if I explain it correctly…
“from the global to the simply” I want to say that first you only have to put the key posses. In block, and then do the inbetweens, etc…
Don’t loose time doing it perfectly, first try to find the correct timing with just a few keys.
For example for an action like a character grabing something you just have to put the following keys:
1º the first walk of the character.
2º when he grab the object.
3º when he stop walking at the end.
Then when you do that and get the perfect timing you have to do the inbetweens.
Do you understand correctly??
