I see the code.

Can the nerf export the mesh ply file? when I run python train_per_scene.py and set the nerf.yaml config file export_mesh=1, and I can't find the ply file.Expect your reply! thank you.

Okay, could you show me your script?

I set the exportation in configs/nerf.yaml like this ：
exportation:
render_only: 0
render_test: 0
render_train: 0
render_path: 0
export_mesh: 1
export_mesh_only: 0
then python train_per_scene.py configs/nerf.yaml defaults.expname=lego dataset.datadir=./data/nerf_synthetic/lego
