#58 Python Error in x3d.py handling of conan_with_texture_files.py

[John W Carlson]

I tried running a python program with x3d.py. I don't see why self.texCoord doesn't have a len(). I even tried initializing texCoord to [] instead of None.

Weird puzzle, but my machine seems to be acting weird.

Sorry but this issue is not understandable or repeatable.

Please start with a valid input and then show the problematic output. Excerpted fragments can help if a model is not sharable. Traceback logs then have some context for understanding.

[John W Carlson]

Understood. That model had serious issues, and I couldn't share it. The
current model is working great!
