Freeze Transforms on the model that will be moving. The wire the Zero Position X, Y, or Z. This will move it on the local axis starting from the frozen position.
Worked on some of the building structures. Tweaked some of the camera FX. Quick transform animation on the flying ships & tweaked their particles. Animated Update
Why not both? I'd recommend most animation to be done as in-place. Calculating offsets with baked-in motion of the root gets really complex. If you need a lurch animation with in-place, you could calculate the animation offset of the new ground position and reverse-transform to get the new root position for the next…
Hi! Can you make the bake files available so one can take a look? A problematic part is sufficient (e.g. arm part). If too large, upload somewhere, share link. Else: Check if transform is applied, no negative scale, no inverted faces.
