Model>Edit Model Meta Data... does not save changes

[Mapsking]

Whenever I open the edit meta data option, for example, say I want to reference a different texture, I can make the changes, hit OK, and then save it, export it, save as, or any combination of the above, and if I re-open the model, it has the same meta data in it. Am I doing something wrong, or is there a bug that prevents saving new information?

Texture changes should be done using menubar -> Materials -> Edit Materials and Edit Groups. Metadata is only directly saved in .mm3d files. Some metadata may be used by the format-specific exporter.

What format are you exporting to and what metadata are you changing?
