Hello, 

Please excuse me for asking this same question.

https://www.renderosity.com/forums/threads/2972673/export-by-python

If you know a solution please let me know...

As I wrote in "export-by-python", import the obj model from python, and  export the model from python  in obj format.

Then the size of the obj file created will be 0 bytes.

Just an import or just an export will succeed.

I don't know what is wrong. . .

If you have any advice, could you tell me.

Thank you.
