How do I make the first keyframe of my animation in maya the "idle pose"?

Hi, I’ve been trying out making animations for UE4 in maya 2016 using the A.R.T and it’s been working great, other than the fact that the mannequin instantly snaps to the first frame of the animation instead of making a smooth transition.

I thought I could just make the first keyframe of my animation the idle pose, so I tried importing the ThirdPersonIdle.FBX animation. The problem is that I don’t know how to copy a pose in maya, and there’s thousands of variables in a pose so copying them individually doesn’t feel feasible.

Thanks in advance for any help, I’ll update the post if I make any progress with the issue!

I did not get what you said exactly but I think you need to know about root motion in UE4.

take look at this page Root motion
