Saving .ma files

8thDec. × ’09

Have you ever tried to save a Maya scene as a .ma (maya ascii) file and received the following message?

Error: File contains unknown nodes or data.  To preserve this information, the current file type cannot be changed.

The tough part is figuring out what is an “unknown” node. To list the “unknown” nodes in any Maya scene simply type the following.
ls -type unknown;

This will list all “unknown” nodes in the script editor. Then replace the X’s with the name of the unknown node and hit enter:
delete XXXXXX

If someone knows of a simpler method to remove all unknown nodes let me know.
