For a two-handed prop, the central problem is contact: which hand or object leads, and which part follows? Choose the animation controls around that relationship rather than treating IK or FK as universally better.
Define who owns the motion
Decide whether the prop follows a leading hand, an independent object or a world-space path. Then identify the supporting hand’s intended contact point. Keep this ownership simple enough that another animator can explain it from the file.
Begin with a short lift, hold and lower action. A static grip can hide sliding that becomes obvious when the torso and shoulders move.
Test controls at the difficult moment
Inspect the supporting wrist, elbow direction and shoulder during the largest movement. If switching control modes is part of the workflow, compare the pose immediately before and after the switch for a visible jump.
Use your rig’s documented snapping and switching behavior. The existence of an IK/FK control does not tell you that a particular rig will preserve a pose automatically.
Bake and inspect the actual handoff
Export the evaluated action through the intended pipeline and replay it with the prop relationship you plan to use in the game. Verify that a Blender constraint or parent relationship has not been mistaken for runtime behavior.
If the game attaches the prop independently, test that exact arrangement. The successful result is stable contact in the destination, including transitions into and out of the grip.
