You’re not alone if your VRM model isn’t behaving in VSeeFace—many hit the same wall. You’ve checked the basics, but something still feels off, and the issue might be hiding in plain sight. A small misstep in export settings or bone configuration can derail the whole setup, and the fix isn’t always obvious. There’s a clear path forward, but it starts with knowing where to look first.
Confirm VRM Model Compatibility and Version
While preparing your VRM model for VSeeFace, you’ll want to verify it’s built to the right standard—specifically VRM0X—since VSeeFace doesn’t support VRM 1.0 and will throw errors like NotVrm0Exception. You must export using Unity 2019.4.31f1; newer versions cause issues, even when using the latest tools. Double-check your humanoid rig, blend shapes, and root hierarchy so nothing’s missing. Ascertain spring bones don’t have empty collider slots or broken references. These oversights trigger avatar validity errors. While updates happen, stick to proven versions unless patches confirm compatibility. Using the latest Unity release might seem smart, but it often breaks VSeeFace support. Stay precise, test early, and verify every export step.
Fix Blendshapes for Blinking and Mouth Movement
Make certain the blendshapes for blinking and mouth movement are properly set up in Unity, because VSeeFace relies on them working correctly. You need to check that the blendshape names match what VSeeFace expects, using exact labels like “Blink” and “MouthOpen.” Confirm they’re assigned to the right facial areas, using Unity’s SkinnedMeshRenderer. Ascertain no other animations are overriding them, using clean animation layers. Verify your VRM’s blendshapes aren’t corrupted or duplicated. Test the model in VSeeFace after each tweak, using real-time tracking to see if blinking and mouth movements respond accurately. Don’t skip testing—small fixes often make the biggest difference. Keep adjusting until expressions work smoothly.
Set Up Bones and Avatar Correctly in Unity
Avatar performance in VSeeFace starts with a properly configured humanoid rig in Unity, so double-check your model’s rig settings to verify they’re set to Humanoid under the Avatar configuration. To guarantee smooth integration and automatic updates in tracking:
- Confirm all essential bones (head, eyes, mouth) are present and correctly mapped in the hierarchy
- Ascertain blend shapes for facial expressions are properly named and assigned
- Fill every slot in the VRM spring bone configuration to avoid export errors
- Use Unity 2019.4.31f1 to prevent compatibility issues that disrupt automatic updates
A clean, accurate setup now prevents major issues down the line. Get this right, and your avatar will respond accurately in VSeeFace with reliable tracking and expression support.
Use Correct Unity & Export Settings
Since compatibility can make or break your export, stick with Unity 2019.4.31f1 to avoid unexpected errors. Newer versions might seem tempting, but they often cause issues during VRM export. When you’re ready, select both the avatar and armature in the hierarchy—skipping this causes “Object reference not set” errors. Double-check your VRM spring bones: empty slots in root bones or colliders break avatar validity. Make sure blend shapes and humanoid bone mappings are accurate. Don’t assume the latest version of Unity works best—follow VSeeFace’s recommended setup. Proper export settings prevent most problems, so always cross-check with the latest version of the documentation for exact requirements.
Update VSeeFace to the Latest Version
While staying on an older version might seem harmless, you’ll want to update VSeeFace to the latest release—currently v1.13.38c4—for the best performance and compatibility. To update VSeeFace to the latest version, follow these steps:
- Download v1.13.38c4 from the official release archive or Deat’s Discord to guarantee you get a clean, secure build
- Check for update notifications in-app (available since v1.13.26) to stay current
- Restart your system after updating to apply changes and clear old processes
- Review updated documentation for any new VRM import settings or feature changes
This keeps your setup stable and bug-free.
Fix Facial Tracking in VSeeFace Preview
If your facial tracking isn’t responding correctly in the VSeeFace preview, start by confirming your webcam works and is selected in the app’s camera settings. Make sure it’s properly recognized so tracking data flows without delays. Adjust gaze strength and facial tracking parameters to better match your expressions. Check that your VRM model has correctly assigned humanoid eye bones in Unity—incorrect setup breaks tracking. Eliminate background distractions that could confuse the webcam. Restart both VSeeFace and Unity to refresh tracking data and clear glitches. These steps fine-tune how well your movements translate, ensuring smoother, more accurate tracking in the preview.

Test Model in a New Scene to Isolate Issues
Since issues with your VRM model might stem from scene-specific settings or conflicting assets, start fresh by creating a new scene in Unity to test it in isolation. This lets you test model in a new scene to isolate issues from clutter or broken references. Import your model directly—no extra plugins or assets. Check the hierarchy to confirm bones, colliders, and blend shapes are intact, especially if you exported from VRoid Studio. Play animations to verify everything works. Once stable, export using Unity 2019.4.31f1 for full VSeeFace compatibility. This clean setup helps catch flaws early and guarantees smoother performance.
Frequently Asked Questions
Does Vseeface Support VRM?
Yes, VSeeFace supports VRM. You can import VRM avatars, use them for face and hand tracking, and tweak blend shapes. Just make certain your model’s set up right with humanoid bones and proper Unity export settings.
Why Is My Vseeface Not Working?
Your VSeeFace isn’t working because you’re likely using an outdated version or your VRM model has missing bones or collider slots. Update VSeeFace, fix those gaps, and guarantee proper blend shapes and Unity export settings to get it running smoothly again.
Does VRCHAT Support VRM?
No, VRChat doesn’t support VRM files directly. You’ll need to convert your VRM model using Unity and the VRChat SDK. Adjust rigging, materials, and animations to meet requirements, then upload it as a VRChat avatar. Tools and tutorials can help you through it easily.
Can VROID Open VRM Files?
No, you can’t open VRM files in VRoid Studio—they’re export-only. You create avatars there, then export as VRM. To view or edit them later, use compatible apps like VSeeFace or Unity, not VRoid itself. It doesn’t support importing VRM files back in.
