Kijiko couple pose rig help please

HI KingBlackCinema   and welcome to S4studio's  You need to set key frames of "control_rig" and "rig" for saving your poses.
Select all the joints of "control_rig" first and choose LocRot in the Insert Keyframe Menu,then select all the joints of "rig" and choose LocRot again.

for one I like to Use my dope sheet to see where I'm placing my keyframes.

for the "Rig" this way I can scrub over them  and then highlight the rig in full like you normally would if you as if you weren't using a rig with out the Control_Rig Attached.

Here is my  How I did mine for  Myself I'm actually doing a fighting scene for my story as well for the rig and so I using this test version of mine  to help you so please bear with me for  my first explanation of this .

1. is the Control_rig your going save Keyframes for this like you would  your rig 

 You can all so save your pose to a pose lib in the blender as well to refer back to later.

2 is the Rig <-- Marked in purple This is What You need to save  "LocRoc" Keyframes to here to get your pose.

AS you can see in my screen below I have my dope sheep open in the bottom, Now if you saved keyframes to the control_rig and  you switch to the Rig one you'll see no key frames in the bar above where I have the 1. is pointing to.

so there your going want to move your lil green bar in the dope sheet back to the beginning, and then LocRot  your frames for the rig ( this marked in the purple bar)part where as the control rig has these.

 I hope this helps (first time explaining )

This is my Test result :



This animation by no way near done I'm still working on it an I still have second part to put to this one once this one is done.
