how can i show leg in the first person camera

#1 I think what you're looking for (the video isn't ready yet) is the renderFirstPerson field in the player datablock. It's set to true in the FPS Kit but false in the Template. It is this field that tells the engine whether or not the player can see their body (legs, torso, and arms depending on animations, camera/eye nodes, etc) while in first person.
