Hello, thanks for this implementation !

I have ran the entire code on my own setup, but encountered a strange phenomenon of artifacts between pixels when relighting using patterns that are not "all 1's". This reproduced for 2 different scenes but does not happen with the provided data.

Have you seen such artifacts or have a way to counter this? any help would be appreciated.

Attached some photos to show what I mean (first image: synthetic image created from shining all 1's (works), 2nd,3rd: new synthetic lights that were used, 4th 5th: the synthetic image created by this implementation projecting these two lights). Notice the artifacts created where the light isn't shining.
