Quality issues about fsgs

[zehaozhu]

Hi @MrNeRF @dlazares

The issue arises from the high weight of the pseudo depth loss applied after 2000 iterations. You can try the new version of code and use the commands for training (need to recompile the simple-knn submodule)

Thank you.

Hi, thanks for your interest in our work. What is your PSNR and LPIPS for this scene?

[zehaozhu]

Actually, we are still tuning settinigs on MiP-NeRF 360 dataset. We plan to release the updated version either this week or the next.

Ok, great. I did not run it again as it takes quite long. So I don't remember theses measures. But overall the rendering output was low quality. I will rerun it when you update the code and report the measures. I am curious how it turns out.

@zehaozhu
I ran this on the bonsai scene and PSNR rises to 29 by 2k iters and then drops to 20 after iteration 2000 when the pseudo depth kicks in. visually I'm seeing similar artifacts to what's happening in MrNeRFs
