Hi, setup_world.json is a manually tuned hyperparameters, as explained in here. What I did, was to write a script to visualize the camera rays from my dataset's camera poses and manually adjust the scenes to center at (0,0,0) (for example, using move_all_cam_vec), and rescale the camera rays to within [-pi, pi]
