making muscle

When I was learning BRYCE I asked my mentor about how to make moving body parts, such as an arm bending, someone flexing their muscle, or simply a person walking. I thought it would be very easy - making the object and getting it to another place. Oh boy was I wrong! You actually have to (using BRYCE) make every individual bone, muscle, and tendon - THEN, you put a layer of skin over the top, then when you move it, you have to make the muscle of tendon constrict making it look like a person is walking. Hey - I guess BRYCE is more life like than I thought.
