Sorry wasn’t paying attention, just saw that it was actually corrected in the lecture!
When setting up the first person two bone IK, Sam selected the left hand for the IK bone. He then says that he’s going to use the other hand for the end effector, but uses hand_l for that as well - I believe this should be hand_r?
Hand_l was also used for joint target, which based on the solution for the third person verion I guess should also be hand_r?
