Perhaps this is a stupid answer since you already said “I know that i need to download single animation with ‘in place’ checked”, but that would solve this. I am using Maximo as well. I simply make sure to have in place checked and make sure that the animation is looping. You can see in the preview if it is smooth or not. If you see that it’s not (like he is ticks back to 0,5 seconds earlier in the same animation) play around with the frame range and/or overdrive. You can always re-adjust the speed of the animation in unreal. As long as you download a smooth ‘in place’ animation, all should run smoothly.
