Ensure Mocha Pro is updated to a version that natively supports Apple Silicon CoreML. Turn off OpenCL if you experience crashes on M1/M2/M3 chips.
: As mentioned, this feature helps to automatically generate a matte based on the tracked object. It can significantly streamline workflows, especially in situations where detailed manual rotoscoping would be impractical.
Troubleshoot Matte Assist ML render failure in Mocha Pro with our verified guide. Learn common causes, step-by-step troubleshooting guides, and verified solutions to get back up and running.
: Matte Assist works best with clean guide strokes. If a layer contains hundreds of manually adjusted control points combined with ML data, the solver can crash. Break complex areas down into smaller, overlapping layers.
Matte Assist ML Render Failure in Mocha Pro: Verified Fixes and Troubleshooting Guide matte assist ml render failure mocha pro verified
To resolve the "Matte Assist ML render failure" in verify that your hardware meets the 8GB VRAM minimum for machine learning tasks
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).
When "Matteist" (ML) renders fail or produce corrupted masks, it is usually due to specific technical bottlenecks:
: This part suggests there's been an issue with rendering using Machine Learning (ML) capabilities within Mocha Pro. Mocha Pro incorporates AI and machine learning to enhance its tracking and effect generation capabilities. Ensure Mocha Pro is updated to a version
: Ensure you have sufficient computational power and memory. Consider upgrading or optimizing your workflow to use available resources more efficiently.
Does the crash happen on a , or is it immediate?
Which and version are you using (e.g., After Effects 2026, DaVinci Resolve 19)? What are your GPU specifications and current VRAM capacity? What file format and resolution is your source footage?
If you are experiencing issues where the after applying the matte, this often indicates that the Matte Assist ML did not properly render to the final output file. Always ensure you see the full, white-filled matte in the Mocha viewer before saving. : Matte Assist works best with clean guide strokes
After verifying with production artists and Boris FX support documentation, the is almost always a resource management or cache corruption issue , not a bug that breaks Mocha Pro permanently.
Before diving into the fixes, it helps to understand the common culprits behind the crash:
