VR IK Body - Support

Been rather stuck on offsetting the hands correctly when holding a object, tried just shifting the hand bone the inverse of where the hand socket is in bone space which worked but obviously caused clipping into the forearm.
i presume i need to use the offset in the effector location too, rather than offsetting it after the ik, but im having trouble getting my head around how to combine the transform of the object grip socket with the hand socket offset transform

To attach object to hand, they usually adjsut position of this object and simply use two commands:
Object->AttachToComponent(AvatarMesh, Name_Of_Hand_Bone)
Object->SetRelativeTransform(Transform_To_Fit_In_Hand)

If you want to adjust position of the hand, don’t add “Transform Bone” node. Instead, add this offset to “Position Right Hand” and use it within “Two Bone IK” node.
There are few useful functions to operate transforms:

• ComposeTransforms (A, B). Adds A to B (order matters). In your case, Compose Transforms (RAttachSocket, PositionRightHand).
• ConvertTransformToRelative(…) - opposite operation. Note, names of parameters are confusing
• InverseTransform - obvious. I’m not sure how it works in you project, so, msy be, you’d need to inverse RAttachSocket before composing it with PositionRightHand.
