Fixing 3D Model Rendering Issues in the Viewer

If your 3D model looks incorrect, glitchy, or incomplete inside the Meshy viewer — but looks fine after downloading — the issue is almost always with your browser or graphics settings, not the model itself. This guide walks you through the most common fixes.

Before changing any settings, download your model and open it in a local viewer (such as Windows 3D Viewer or any offline 3D tool). If it looks correct there, your model is fine — the steps below will resolve the viewer issue.

The Meshy viewer relies on WebGL, a browser technology for 3D rendering. Outdated browsers can struggle with it.

Make sure you're running the latest version:

• Chrome: Menu → Help → About Google Chrome → update if prompted

• Firefox: Menu → Help → About Firefox → update if prompted

• Edge: Menu → Help and feedback → About Microsoft Edge → update if prompted

If updating doesn't help, switch to a different browser entirely. Chrome tends to have the best WebGL support and is our recommended browser for Meshy.

Hardware acceleration lets your browser use your GPU to render 3D content. If it's turned off, the viewer may produce incorrect or degraded output.

1. Open Chrome Settings (chrome://settings)

2. Search for "hardware acceleration"

3. Toggle Use graphics acceleration when available to ON

4. Click Relaunch

1. Open Firefox Settings (about:preferences)

2. Scroll to Performance

3. Uncheck Use recommended performance settings

4. Check Use hardware acceleration when available

5. Restart Firefox

1. Open Edge Settings (edge://settings/system)

2. Toggle Use graphics acceleration when available to ON

3. Click Restart

Outdated GPU drivers are a common cause of WebGL rendering glitches.

• NVIDIA: Download the latest drivers from nvidia.com/drivers

• AMD: Use AMD's driver support page

• Intel: Use Intel's Download Center

After installing, restart your computer and reload Meshy.

GPU drivers on Mac are bundled with macOS system updates. Go to System Settings → General → Software Update and install any available updates.

If none of the above steps resolve the problem, please reach out to our support team with the following details:

• Your browser name and version

• Your operating system

• Your GPU model (if known)

• A screenshot or screen recording of the rendering issue
