How to save feet position with retarget? Missing IK info maybe?

Hey all. I’m trying to save an idle animation from Paragon character Greystone and use it as the idle animation for Manny.

Everything looks great up until I actually try to apply the saved animation to Manny as the new idle animation. The legs bend and feet are positioned wrong. Maybe I’m missing some sort of IK information for the feet or something? I’m just not sure.

You can see it looks good on the retarget tab.

The exported animation also looks good.

But once I apply the saved animation to Manny, his legs pull inwards and don’t move properly.

My terminology may be wrong and what I’m doing in the editor may also be considered incorrect. I’m pretty new to this so feel free to talk to me like a newbie.

Any help or tutorials are very appreciated. Thanks!
