unilab.visualization.interactive_playback.build_offpolicy_play_env_cfg_override(algo_name, cfg, *, root_dir)[source]

Build the off-policy play override, including backend render intent.

Training and playback deliberately use separate adapters: an IsaacSim renderer must be selected before the worker’s Kit INIT handshake, but learner/collector environments must stay on the no-rendering experience.

Parameters:

  • algo_name (str)

  • cfg (DictConfig)

  • root_dir (str | Path)

Return type:

dict[str, Any] | None
