this is a new and improved IK that i invented, its 100% accurate and will not cause any slowdown, since it runs incredibly fast
my average 1.8 dual core can handle 370 chains without dipping below 60 fps, thats fast.
this chain can also handle any length of arm, in any combination, it cannot glitch.
the arm itself is very simple to setup and requires only 8 actions and 4 events to function 100% normally (2 of the events only require 1 action, and 1 of them requires 2, the other contains 4)
in my cap i added alot of extra bells and whistles, but the simplicity of the chain can be seen in the IK arm group, the canvas is obviously not needed.
