Hello @SophieRobbins, Make sure all of your frames are baked down prior to export to better keep your animation intact. Having no animation data on frame 1 can typically cause issues (but not this kind from what I recall). Double check that your animation is actually keyframed at those start, mid and ending points and that…
Okay, so, I've been working on this model for a while (and other models) and I'm currently exporting from Blender in DAE format because OBJ doesn't have vertex colours (which I'm using for hair colour) and FBX makes my models not line up properly. So I've settled on DAE which exports animation correctly, comes with vertex…
Thanks, Arthaven! When I lost my animation due to user error (don't ask, I'm still learning...) and made a new animation, that one exported out and has come into Marmoset just fine. I'm not entirely sure what the difference is. Maybe I accidentally didn't keyframe a bone the first time?
