IK Booster has the option to “fix” an item, which locks the position of the item’s controller. When this option is not active only the current hierarchy will be solved with IK. When this option is active all hierarchies in the object will be solved with IK. IK Booster provides a global IK on/off switch. This option enables and disables all bone dynamic functions for the object that IK Booster has been applied to. The IK Booster Track is located at the bottom of the viewport windows. If the DopeTrack is not active, the IKB Menu will be located on the right side of the IK Booster track. If the DopeTrack is active, the IKB Menu will be located to the right of the DopeTrack. The IK Booster menu has several options to work with. Current Item - With Current Item mode, if you create a key on an item, it only creates the key on that item.Parent + Child - In this mode, if you create a key on an item, it creates a key for that item and every parent up that item’s chain, and every child down the chain.
