User checks bTakeRotationFromEffectorSpace before changing EffectorLocation from BoneSpace to WorldSpace. Once set to World Space, the 'End Effector' section of properties becomes hidden and bTakeRotationFromEffectorSpace is no longer visible to uncheck. This results in AnimNode_TwoBoneIK.cpp continuing to use the variable bTakeRotationFromEffectorSpace to determine the EndBoneCSTransform, when it should now be determined from World Space.
It is suspected that "...the lines in AnimNode_HandIK that check both bTakeRotationFromEffectorSpace and bMaintainEffectorRelRot to modify the EndBoneCSTransform should be guarded by "if ( bBoneSpace )
{ ... }"."
Entered bug per instruction, however, I currently do not know how to reproduce this. Reached out to Matt Williams for repro steps.
