this week We have learned about constraint and animation. Because keying frame is a little complex, I just create a circle as a controller and using script to links each element together . If I want to change speed at any frames I can only changing one parameter to control all things. Then I used some noise function to control the speed of wheels.
We also learned something about mash. I am also interested in the workflow of the mash UI, however I hardly ever used the mash part in maya, so I will cost more time to know more about these.
