🔴 This is by far the most common reason for the failure. Machine learning models require a significant amount of dedicated video memory to process an image and its AI mask. The official minimum requirement for ML tools in Mocha Pro is 8GB of VRAM . If your GPU has 4GB or 6GB of VRAM, you will likely encounter this error, as Mocha Pro simply cannot load all the necessary data into your GPU's memory.
Open Mocha Pro and navigate to (Ctrl+Alt+P on Windows, Cmd+Comma on macOS). Click on the GPU tab.
: On Linux systems using virtual GPUs, this error may specifically trigger a CUDA error ; ensuring native hardware access can resolve this. Configuration Checklist
While you're sorting out hardware issues, you can sometimes change how you work to avoid the error. matte assist ml render failure mocha pro verified

For example, are you interested in:
Ensure that your version of Mocha Pro fully supports the version of the host app you are running. For example, using an older version of Mocha Pro with a brand-new release of Adobe After Effects or Foundry Nuke can cause API errors during the render handoff.

with Compute Capability 6.0+ (Pascal architecture or newer) or an AMD Radeon PRO series card. : Requires Apple Silicon (M1/M2/M3) with macOS Monterey (12.0) or later. Driver Check
By systematically isolating the hardware runtime, clearing out corrupted temporal caches, and scaling down VRAM pressure, you can bypass the Matte Assist ML render failure and restore stability to your VFX masking pipeline.
If the error persists, you can find the exact point of failure by checking the Boris FX log files. Navigate to your system's application data folder: %APPDATA%\BorisFX\Mocha Pro\ macOS: ~/Library/Application Support/BorisFX/Mocha Pro/ If your GPU has 4GB or 6GB of
