The Write Animation FBX node
When to use it
Write FBX exports a mesh. This exports the animation instead - the skeleton plus its bone keyframes, read straight off the Animation wire, so whatever a Pose Animation Sequence node baked into those keyframes upstream comes along with it. Use this when the take itself is the deliverable; use Write FBX when you need geometry.
There is no file-path pin - the Write FBX button pops the save dialog itself, same as the mesh exporter.
An empty or invalid Animation input fails with a node error before any dialog appears. Float curves - morph target weights and the like - are not part of the animation wire, so they never reach this file; only bone transforms do.
How to use it
- 1
Connect an animation to the Animation input pin
- 2
Tweak axis / scale / ASCII settings on the details panel
- 3
Click Write FBX — choose a destination, file is written
Pins
| Pin | Type | Description |
|---|---|---|
Animation |
Animation | The animation to save. Its skeleton and bone keyframes come through, including any in-graph pose edits. |
Settings
| Setting | Type | Description |
|---|---|---|
Coordinate System |
Choice | Handedness written into the file's header, so the app opening it knows which way round the skeleton is meant to be. |
Front Axis |
Choice | Which axis the file should call forward. |
Up Axis |
Choice | Which axis the file should call up. Set it to Y for Maya, leave it on Z for anything coming back into Unreal. |
Scale |
Number | Multiplies every bone translation on the way out. Leave it at 1 to keep the skeleton at the size it is here. |
Export As ASCII |
True/False | Writes readable text instead of binary. Handy when you need to look inside the file, but it runs about five times bigger. |
Available in Mesh Morpher Graph and Mesh Morpher Studio.
