[mtoa] Using dirmap to update paths


How can you update the paths used to load textures, standins, or volumes? Use dirmap.

You can use dirmap to update the paths for the following nodes:

  • aiImage (Image Name)
  • aiStandin (Path)
  • aiVolume (Filename)
  • MayaFile (Image Name)

For example, if I have a scene file that uses Linux paths like /server/assets/textures/noicon.tx, I can do this:

dirmap -en true;
dirmap -m "/server/assets" "D:/Assets/";

After I run that, when I load a scene Maya will replace “/server/assets” with “D:/Assets” in all file paths.

You can test your directory mapping (dirmap) like this:

dirmap -cd "/server/assets/textures/noicon.tx";
// Result: D:/Assets/textures/noicon.tx //

So:

  • Enable dirmap with dirmap -en, and then create a directory mapping with dirmap -m
  • Load a scene and the dirmap is applied.

TIP For batch rendering, you can use a pre-render script to apply dirmap.

BONUS TIP: dirmap does not update a path if the path is valid. dirmap replaces paths that cannot be resolved.
