I have tested both omni-re and street gaussian implementations within drivestudio. As the number of iterations increase, I noticed that the file size of the checkpoint decreases

I have also tried to view the scene in a 3D viewer (birdeye-view) I noticed that there are a lot of black holes (50k iter): For 100k, it gets significantly worse.

I did not change any hyperparameter, except for the number of iterations.

After 20000 iter, it only did culling but not duping. That's why it is getting smaller I think.
