Syntax
USTRUCT (
Meta=(DisplayName="Basic IK", Category="Hierarchy", Keywords="TwoBone,IK", NodeColor="0 1 1"))
struct FRigUnit_TwoBoneIKSimplePerItem : public FRigUnit_HighlevelBaseMutable
Remarks
Solves the two bone IK given two bones. Note: This node operates in world space!

   |
float | StretchMaximumRatio | The maximum allowed stretch ratio |
   |
float | StretchStartRatio | The ratio where the stretch starts |
   |
float | Weight | The weight of the solver - how much the IK should be applied. |
