Animations

It is of course possible to export animations with your skeletal mesh. You can use the Action Editor in the Dope Sheet window to have multiple animations in one scene or use the NonLinearAnimation.

For the Action:

1. Select your SkeletalMesh and open the Animation Properties panel (Do not forget to set the Armature as Export recursive).
2. Inside the Dope Sheet window, select Action Editor mode and create your animations on actions ( /!\ Don't forget to use fake user to not lose your animation! )
   • You can use a driver for the Morph Target.

3. In the Animation panel Properties you can set the animations property of your skeletal mesh like Animation time, Quality, and select the animations to export.

Note: if your animation is not a cycle, set 'Offset at start frame' to 0. 'Offset at start frame' is set to 1 by default because in the animation cycles, Unreal will play the first and the last frame, so twice the same.

With an offset of 0 in Unreal I have this:

With an offset of 1 in Unreal I have this:

For the NLA:

1. Select your SkeletalMesh and open Animation Properties panel (Do not forget to set the Armature as "Export recursive")
2. In Animation panel Properties you can set the animations property of your skeletal mesh like Animation time, Quality.
3. If you just want the NLAnimation set Action to export as Not exported and check the box Export Nla with your desired name.

Export animation with Proxies

If you want to export the animations of a Skeletal Mesh with Proxies, you should set 'Export recursive' on the proxy. Tick 'The armature is a Proxy?' and select the child proxy.

For importing animations with import script, Blender For Unreal Engine needs to know the skeleton name in UE4. This is detected automatically, but for the proxy, since the armature doesn't have the same name, it will have to be defined manually.
