For work purposes, I have generated the shifted LiDAR projection condition from trajectory 049 and would like to use it as input to the diffusion model for inference. However, the existing script render.py performs novel view synthesis (NVS) operations on its own and does not allow for the input of pre-generated LiDAR conditions. It seems that sample_condition.py requires the full Waymo dataset (I have only downloaded the ready-made data provided by the project). Do you have any suggestions?
