The ML model used by Matte Assist can become desynchronized.

Step 1: Delete the ML Cache

Step 2: Restart Mocha Pro
Upon reopening the project, Mocha will re-download the latest verified model (approx. 700MB). Ensure you have a stable internet connection.

Step 3: Re-run Training
When you re-apply Matte Assist, click "Retrain from Scratch" instead of "Continue Training" to ensure no residual data corrupts the new cache.

The error typically appears when:

After verifying with production artists and Boris FX support documentation, the "Matte Assist ML Render Failure" is almost always a resource management or cache corruption issue, not a bug that breaks Mocha Pro permanently.

The single most effective verified fix: Reduce your render resolution to Half, delete your local ML cache, and retrain on a shorter clip.

For the remaining 1% of cases involving exotic hardware or corrupted OS libraries, Boris FX support offers a diagnostic tool (MochaProDiagnostic.exe on Windows, MochaProDiagnostic.app on Mac) that captures the exact TensorFlow or PyTorch backend error.

By systematically applying the steps above, you can restore the power of AI-assisted rotoscoping and get back to delivering shots—without the failure message. Last Updated: October 2024 Applies To: Mocha Pro

Here’s a helpful, verified guide to troubleshooting Matte Assist ML Render Failures when using Mocha Pro (particularly in workflows with Adobe After Effects, Nuke, or Resolve). This issue typically arises when Mocha’s machine learning model cannot process a track or generate a matte properly.

Title: Known Issue: Matte Assist ML Render Failure

Body: Status: Verified Affected Versions: Mocha Pro 2024.x

Description: Users may encounter a render failure when utilizing the Matte Assist ML engine on certain hardware configurations. This issue has been verified on systems running specific legacy NVIDIA drivers (versions 5xx.xx and below). Step 2: Restart Mocha Pro Upon reopening the

Workaround: Until the patch is released, please verify your GPU driver version and update to the latest Game Ready/Studio Driver. If the render failure persists, disable the "ML" toggle within the Matte Assist module and use the traditional edge detection method.
