Some dynamic cars and pedestrains disappear in render result image

[jycc1991]

I use the following command in your readme.md to render waymo 114 data
python train.py -s "./data/waymo/processed/training/114" --expname "waymo" --model_path "./work_dirs/phase1/recon/114"
but the the rendered result image looks strange,many dynamic cars and pedestrains disappear according to the original image,can you show me how to achieve the state of art performance in your paper?
thanks
