Unexpected blank lines for rendered images

[taeksuu]

Hi, thank you for your great work!!

I've set up the environment using the given 'env.yml', but as I trained the coarse model I noticed there were unusual blank lines in the plotted images for canonical shape like the attached figure. Those blank lines also appear when I generate the given outputs using 'test.py'.

I believe it's the problem with pytorch3D's renderer, but I was wondering whether you've seen similar outputs during your experiments.
If so, would there be a way to fix this problem??

Thank you in advance.
