In accord with Erlang doc (File module) this error could means (depending on what function was used):
- The directory does not exist;
- The file does not exist;
- The file could not be found in any of the directories in Path.

as the crash occurs exporting the materials ({e3d_obj,materials,3}) maybe you could have some material setting wrong. Maybe a material with texture pointing to an image file or directory not found in your system. Take a look in such possibility.
