Exception: Access to the path '_______' is denied

[ahon-s]

What is the problem?

[When downloading some OBJ files, I noticed that they don't have external MTL files, but their first line is "mtllib ". When running the program in this case, it throws an exception-Exception: Access to the path '________' is denied.]

What should be the expected behavior?

[I hope to handle this situation by ignoring the 'mtllib ']

How can we reproduce this? THIS IS IMPORTANT. What steps did you do to trigger the problem? If this is an issue with processing a model, YOU MUST include a copy of your model uploaded on Google Drive or Dropbox (otherwise we cannot reproduce this) along with the command line parameters you used to process it.

[It is possible to reproduce the exception in OBJ files that do not use external MTL files by adding 'mtllib' on the first line]
