About the way sampling rays

[daipengwa]

Thanks for you brilliant work. I have a question about sampling rays. Since I want to render a patch, I set the parameter 'random_sample' in scene101.sh and in train_ft.py line 917 as 'patch', then run per-scene optimization on scannet scene0101_04. In this way, the performance is inferior (~2 drop on PSNR) to randomly sampling rays. Is my setup correct? Have you ever tried the patch sampling? Thanks

hi @daipengwa Did you manage to figure out why? I'm also trying to use patch_wise sampling.
