I realized that for nerfstudio, after exporting the gaussian-splat from the checkpoint, nerfstudio only outputs a .ply file containing the gaussian-splat model, without the cfg_args file.
I know that to run c3dgs, the cfg_args file is required. However, the parameters of the splatfacto model in Nerfstudio differ from those in the original gaussian-splatting repo. What should I do now? Thank you.
