Class Policies
Attendance: Thee or more unexcused absences result in the drop of a letter grade. Please notify the instructor of an absence. Students are responsible for the information missed during the class.

Participation: It is important for everyone to participate during class discussions and ask questions whenever needed. Participation is part of the overall grading, and students are expected to focus on the topic at hand.

Assignments: Each week will feature a short assignment that leads into a finished character rig. We will rig two characters in the course - one simple one with easy skinning and then a more complex one that requires more skinning. Assignments are to encourage you to stay on task with what we cover each week and become familiar with the topics covered in class. You are required to notify the instructor of any late or unexcused assignments. Otherwise it will impact your final grade.
*Assignments should be turned in on the class box site by Sunday night for Section A and Monday night for Section B

Rigging Projects
1) Character 1: Fully rigged - Skinned, Reverse foot, FK/IK arm Switch
2) Character 2: Fully rigged - Skinned, Reverse foot, IK Spline Spine, FK/IK Arms, Space Switching, Face Features, advanced features for extra credit

Grading: 
Weekly Assignments (13 assignments) - 20% (4 points each)
Character 1 - 30%  (100 points)
Character 2 - 50% (100 points)

0=not turned in, 1=incomplete or not working, 2=requires improvements, 3=great but needs slight adjustments, 4=awesome, everything works

Explanation - Since each assignment builds up to a finished character rig, grading emphasis is placed on the completed characters since they are the end product. Students can put as much time into making improvements and/or additions to the rigs after an assignment is turned in. Character 2 is considered the "final project" and will have the most grading criteria due to the deformation, rigging systems, and facial features it requires. That being said, if students work hard each week to keep up with with the assignments, less work will be required in the end to complete the fully rigged characters.
