Results shifted to some side

[julzzheng]

Hello,

thank you for this work first of all. Currently I'm trying to reimplement this work in Pytorch and I'm facing a specific problem.

My problem is, that the rendered images seem to be shifted to a wrong direction, if I have to describe it like someone moved the camera. That's why I wanted to ask if someone could have an idea where I did my mistake.

I tried to follow this implementation of Nerfies as close as possible but written in Pytorch.

Here I have two example pictures, with the left being the rendered one and the right being the ground truth. I'm thankful for any help here.
