I saw this video: https://youtu.be/Nc6ewpdBzxo, and I am trying to replicate it. See Time (14:30) to see him put together the drivers. The Drive Equations are Tan(var/2) and Tan(var/2)-1.
It uses a simple shape key drive system to make the mine craft arm bend correctly. I was having trouble getting the drivers to work and I think I have figured out why. My value for the input variable system is different than in the video. In the video it is 0, but my value for the input variable is -1.571 (-90 deg).
How do I correct this? I could really use you guy's help!
