Export MDD

The export MDD plugin for Modo 701, allows you to easily export mesh deformations to other applications. This can be useful for caching Dynamics Softbodies or for taking your animations to other applications for rendering.

As it's implemented as a native command plugin, it's much faster than it's 601 scripted predecessor. Just as a quick example of the speed increase; I did a quick test, exporting 24578 vertices over 120 frames. In 601, the script took 2min 20seconds. In 701, the plugin takes 25 seconds. So, quite speedy in comparison.

There are a few simple arguments that provide extra (optional) control:

  • start
    This sets the start time to export from, measured in seconds. If this argument is undefined, the plugin will use the current start time as defined by the timeline.
  • end
    This sets the end time to export to, measured in seconds. If this argument is undefined, the plugin will use the current end time as defined by the timeline.
  • filepath
    This sets the file path (the folder) to export the MDD files to. This is useful when running the command through a script which defines the path. If this this argument is undefined, a file path dialog box will launch, asking the user to choose a path.
  • step
    This sets the number of steps to export per frame. A step of 1.0 will export the point positions at every frame. A value of 0.5 will export the point positions at every other frame. A value of 2.0 will export the point positions at every frame and every half frame...etc. If this argument is undefined, the plugin will assume a default of 1.0.
  • name
    This sets the name of the MDD file, so the final file created will be in the format: <filepath> / <name> .mdd. This is mainly for the purposes of scripting, to allow for a script to define the names of the various files to fit into an existing pipeline/file structure. If this argument is undefined, the plugin will use the item name as the MDD filename.

To install, simply extract the zip file into your user config folder. Restart modo and the Export MDD command should now be available at the bottom of the Animate Menu.
