Bake Animations feature allows users to easily export
animation data in the
Alembic (.abc) file format for use in other 3D software.
How To Export¶

- In the
Timeline, set the frame rate for the animation according to the looping or planned length of the
- Go to the polygoniq
Bake Folderand Click on
Export Animation. The
exportmight take some time depending on the size and complexity of the asset and number of key frames.
.abcwill be located in the folder you chose. The
.abcfile is always named the same as an object in
When exporting data, the scale will always be multiplied by 100.
For alignment with
common scale conventions used in other software such as
Unity, the exported object is scaled up by a factor of 100.
Caution: Large file size!
Keep in mind that the exported
Alembic file can become very large, especially when exporting
geometry or complex
How To Import To Another Software¶
- Open the
Content Drawer, click on the
import button, and select your
abc.file. This will open the
Alembic Cache Import Options.
- It is important to select "import type as Geometry Cache." Make sure to set the start frame to 1 and ensure the end frame corresponds to the frame you chose in Blender.
- (Optional) Set rotation X to 90 degrees to convert from right-handed to Unreal's left-handed conventions.
- Drag and drop the asset into the scene.
- Play the animation.
Unreal only supports triangles and quads
Unreal Engine may show you:
Unable to import mesh due to a face consisting of 6 vertices, expecting triangles (3) or quads (4).
That happens when you attempt to import geometry which contains single edges or vertices. N-gons are triangulated automatically. One possible solution is to select the asset, go to edit mode, duplicate a single vertex, use "Shift + G" (Select Similar), choose "amount of collecting edges" and press Del.
