Hi Judisak, I don’t have any tricks to matching when switching. I didn’t build snapping into the rigs. But here’s some advice for doing it by eye.
-Make sure you key both the IK and FK on the switch.
-switch over 1 frame (key both IK and FK on both frames as mentioned above)
-try to avoid switching at all and stick with either IK or FK on that body part for the entire shot (probably not possible in this circumstance)
-try to switch during a move so it is easy to flip the frames and match the motion – OR
-try to switch when it is perfect still, so when you flip the frames you can see when it isn’t matching and tweak it easily.
(The last 2 tips depend on the situation. 1 way is usually easier in different shots)
Hope that helps.
