So to simplify things lets just say I have a cannon object that does a 360 when it shoots and a cannonball object that flies out. I need to export this file as an fbx so what I need is one animation since it will be controlled via a script. I have learned to make animations for fbx files using something called the action editor in Blender. I name the animation there, click the F which I believe stands for fake user, and export it to Unity without a problem. The problem is that those have always been rigged characters that have every part connected. Now I have been trying to do this with separate objects but when I try to use one animation they get all screwed up. I have also tried parenting the objects to each other without changing the transform.

  • $\begingroup$ I don't think so. I especifically need one animation. I don't want to export an fbx with two separate animations. $\endgroup$ – luigi Feb 19 '15 at 21:48

Okay so after much trial and error, it seems that the only possible way to do this is with an armature. Just rig the armature to all the objects you want to animate and create one action animation in the armature. I have 4 bones in the armature, none of which are actually connected with each other (both the bones and the objects) and I just animate the bones. ! animation to export to Unity with many different moving parts.

If you make a parent object of 2 objects, then you can access both those objects in the animator of the parent object, then using the animation panel to animate the 2 different objects and transition between animations in the parent's animator.
