morganmc, I came into a similar, if not the exact same issue over the weekend when I was trying to add a First Person mode to my currently Third Person game.
The idle animation loop for the Rifle Animset Pro contains a wobble, which is OK in Third Person but not in First Person. I do have an “Aim” event for Third Person which zoom in to an over the shoulder view similar to what you have done. I want the wobble to stop when zoomed, similar to how you want the wobble to stop when in First Person.
Right now, the only way I think this can be solved is to edit the idle animation loop and remove the frames that do the wobble. Heck, you can just have the first frame if you don’t want any movement during idle at all, although the character will look frozen. Luckily this can be done in Unreal itself. Just make a copy of the Idle animation loop, open it in the editor, and then edit it by right-clicking on the time bar and remove frames. Then you will need to replace the original loop in your blendspace with your new loop.
This is all off the top of my head, so if it doesn’t work the first time, I’ll edit this post when I get home.
