Maya Playblast OpenImageIO

Playblast using OpenImageIO (OIIO) to save image files inside Autodesk Maya.

This project is a work in progress, the goals are:

• Simple plug-in command, relies on python wrapper to do the heavy lifting.
• Command flags should be logical - we will not maintain compatibility with 'maya.cmds.playblast'.
• OpenImageIO should be used for file writing and any image manipulation.
• Maya playblasts images should be able to be written in linear ACES colour-space, using OpenColorIO for implementation of colour conversions.
• 3D Motion Blur should be possible. This means playblasting more than one image, then averaging the resulting pixels together. This should be done efficiently.

Features

• Work in progress.
• See goals above.

Usage

• Compile plugin using CMake.
• Copy library (.so file) into plugin path (MAYA_PLUGIN_PATH)
  • For example, create the following directory and copy the .so file into it:
    • /home/$USER/maya/2016/plug-ins/
• Open Maya
• Load "playblastOIIO", using MEL or Python.
  • MEL:
    • loadPlugin "playblastOIIO";
  • Python:
    • maya.cmds.loadPlugin("playblastOIIO")
• Playblast the current Maya scene:
  • Python:
    • maya.cmds.playblastOIIO(filepath='/path/to/output_filename', startFrame=1, endFrame=24, imageSize=(1920, 1080))

Building and Install

Dependencies

• C++ compiler with support for C++11
• CMake 2.6+
• OpenImageIO 1.2+ (https://sites.google.com/site/openimageio/home)
• Autodesk Maya 2016+
  • Older versions could work by have not been tested

Build

To be written.

Install

To be written.

Limitations and Known Bugs

• On Linux build there is a symbol clash between boost inside Maya and OpenImageIO, this causes any parallel computation to crash Maya immediately. Because of this bug the reader has been forced to use a single thread (disable boost) for all image computation inside OpenImageIO.
