What is Rokoko?
-
Rokoko isΒ a motion capture (mocap) system that includes AI tools for capturing and animating motions.
A free AI tool that allows users to:Β
- Upload a video of a person movingΒ
- Record themselves with a webcam or phoneΒ
- Automatically extract the motion file π‘ It is a great tool for capturing and animating motions for my NPC character in UE5
Experiments Process:
- Select a short video (under 15 seconds).
- Use Rokoko to auto-rig the animation.
- Export the rigged animation.
- Import and adjust the bone positions as needed.
- Add the animation to the scene β> Done!!!
Attempts:
-
Upload a figure skaterβs video (3D real-life photo)
I notice it is losing the motion details.
Rokoko - AI Auto Rig
UE5 - Add the NPC Animation to the Scene
-
Upload an animation (2D Character)
-
2D animation character - Mickey Mouse
I chose this character because it has abstract motions. -
As expected, Rokoko cannot recognize the motion correctly, not even 20%.
-
Next steps:
- Find engaging short videos to incorporate into the NPC character interactions.
- Develop a method to attach animations to custominzed character model.
Conclusion:
β οΈ Tips for using Rokoko
- Keeping animations simple and similar to NPC movements will yield the best results.
- It only matches the UE5 Mannequin Skeleton
