Compatible Nuke versions: 13.0 or later

Compatibility: Windows

OpenInMocha speeds up the Nuke → Mocha Pro workflow by launching Standalone Mocha with the correct footage, frame range, frame rate and pixel aspect, and by reusing existing .mocha projects instead of creating duplicates.

  • Launches Standalone Mocha Pro with footage from the selected Read node

  • Creates a new project with correct settings when no matching project exists

  • Reopens an existing .mocha project if one already matches the footage

  • Accessible from the Nuke menu, custom hotkeys, or W_Hotbox

  • Windows only (Nuke 13+, Python 3 recommended)

Installation

  1. Download

  2. Copy the OpenInMocha folder into your .nuke directory.

  3. In init.py, add:

    import nuke
nuke.pluginAddPath("OpenInMocha")

    (If import nuke already exists, add only the pluginAddPath line.)

  4. Restart Nuke.

  5. Select a Read node and run Extra → Open in Mocha Pro, press Shift+M, or use W_Hotbox.

Configuration

Edit openinmocha_config.py to change menu location, shortcut, Mocha path, debug popup, and default output folder.

Requirements

  • Nuke 13+ (Python 3 recommended)

  • Standalone Mocha Pro

  • Windows (macOS / Linux not supported)
