Basics - How to import a Mixamo animation in UE4
The following are basic and generic instructions to correctly import an animation from the Mixamo website into an Unreal Engine 4 project. Playing with the options in Mixamo and Unreal Engine 4, more advanced workflows are possible.
- in the Mixamo website, select the same exact Character you imported in your UE4 project (IMPORTANT - Mixamo fits the animations over the selected character, so it's important to select the correct character first)
select the animation you want to download. The preview will update showing the animation applied to the selected character.
- press the Download button
- in the Download Settings dialog, set:
- Format to FBX Binary;
- Skin to Without Skin.
- press the Download button and download the FBX file;
- import in Unreal Engine 4 the downloaded FBX file (you can drag & drop the file in the Content Browser, or use the Add/Import > Import to option);
- in the FBX Import Options dialog:
- use the Default settings, if in doubt press the Reset To Default button;
- set the Skeleton option to the skeleton asset of the matching Mixamo character (IMPORTANT - this we'll associate the animation to the specified character skeleton);
- press the Import or Import All button.
Done :) You'll find the Mixamo animation in the Content Browser.
Now you are ready to retarget this Mixamo animation to character using the UE4 Mannequin.
