Unreal Engine 5.8 introduces a brand new Markerless Mocap plugin available inside the engine. Like the entire Unreal Engine, it is completely free to use.
Unreal Engine 5.8 can now turn an ordinary video into motion capture without suit or cloud subscription. It runs locally on your own machine, it's free, and the results are genuinely good. Naturally, that's led a lot of people to declare every other mocap tool officially dead. Is that true? The answer is “maybe”. The feature is impressive enough to be worth taking seriously, and this guide walks you through getting it running and bringing the result back into Blender.
The new capability lives inside Unreal's MetaHuman system, powered by the Markerless Motion Capture plugin. You feed it a single-camera video and it extracts either body or facial animation, or both. You can preview and apply it on a MetaHuman right aways.
Quick Start Guide
(a text guide is available below)
1. Install the pieces. Install Unreal Engine 5.8 and enable MetaHuman Core Data during installation or add it later from the install options (it's about a 6 GB download). Then head to Fab inside the Epic Launcher, search for "Markerless," and install the Markerless Motion Capture plugin (another ~5 GB).
If the plugin refuses to install, close the Epic Launcher and relaunch it as administrator.
2. Enable the plugins. Create a new project, then go to Edit → Plugins, search "MetaHuman," and enable MetaHuman Animator, MetaHuman Animator Markerless Motion Capture, and MetaHuman Core Tech. MetaHuman Creator is optional, but enabling it lets you preview the capture in-engine. Restart the engine when prompted.
3. “Ingest” your footage. Go to Tools → Ingest Server, then Tools → Start the Link Hub.
4. In the new window, switch to Capture Manager. Click Add → Mono Video Ingest. Point the Take Directory at your footage folder, select the clip, and Add to Queue. Hit Start.
If you get an error, open Settings, enable Use Third Party Encoder, and point it at ffmpeg.exe anywhere on your system (most machines already have FFmpeg; if not, grab it from a quick Google search).
5. Create the performance. Close Link Hub. Back in Unreal Engine, go to Content → Capture Manager → Imports → Mono Video Ingest, open your take, then right-click → MetaHuman → Create MetaHuman Performance and open it. Select the capture data and enable Body Tracking or Facial Tracking, or both. Click Process. This is the slow part. Expect it to take 15–30 minutes for a 30 seconds clip.
Tip: if you're tight on VRAM, open a fresh empty world and shrink the viewport so Unreal isn't wasting resources rendering the scene while it works.
6. Preview it. To preview the mocap, assign it under your performance's Visualization settings and you'll see your capture playing on the character. Note: You need an assembled MetaHuman in your project. Creating one is beyond the goal of this guide (the video above contains basic instructions).
7. Export the Animation. Finalize the animation from the Performance by pressing the Export Animation button.
From here you can easily apply the motion capture on MetaHumans in your project, use it in Level Sequences, and retarget it to other skeletons Unreal.
To export it out of Unreal for Blender, Maya, etc., right click on the animation asset you created in Step 7 → Asset Actions → Export.
Details about using the animation and exporting are available in the video above.
Is this the ultimate Mocap Solution?
The final quality is amazing, and being free and local is a serious advantage. But it doesn't fully wipe out the competition. Processing is slow, the hardware demands aren't trivial, and because the feature is brand new it's still full of small gotchas (expect your first few attempts to be bumpy). It took a full day to work everything out the first time around.
Because it's single-camera, the quality is best when your subject stays relatively grounded. In those cases it can look close to a Rokoko suit capture!
The trade-off for "free and local" is resources. Expect to set aside at least 15~20 GB of disk space for the engine and plugins, 8 GB of VRAM as a bare minimum, and 32 GB of system RAM. Processing is also slow: roughly 20–25 minutes for 30 seconds of footage.
Alternatives
So my honest answer is: it's an excellent new option, not a universal solution.
Depending on your needs, the alternatives still earn their place. QuickMagic, FlowStudio and Pinoc still win on sheer simplicity (drag, drop, done). XR Animator still matters if you need real-time capture. Marionette remains a streamlined, likely faster studio tool.
And for going beyond single-camera limits, multi-camera solutions like Mimem (the easiest) or the fully open-source FreeMocap are worth exploring.
Unreal 5.8 markerless mocap absolutely raises the bar for free, single-camera capture. But "best out there" still depends entirely on what you're trying to do.
