How to create my own dataset for SimEngine

[EkSulfur]

What should I prepare? How can I transfer it into supported format? Thanks!

Thanks for your interest. Could you clarify what source dataset and data format you are using?

SimEngine does not currently provide a generic converter for public datasets. The existing data preparation pipeline is designed for nuPlan scenes and assumes that the corresponding MTGS reconstruction assets and calibration metadata are already available.
To better understand your use case, please provide:

• The source dataset and its directory/data format

• Available camera calibration and ego/sensor poses

• Whether agent trajectories, map data, and traffic-light states are available

• Whether you already have compatible rendering assets

If your goal is to reuse the existing rendering assets for nuPlan-based scenes, modify the ego or surrounding-agent behavior using your own models, and then save the resulting rollout as a new SimEngine scenario, this should be technically feasible. However, the current public WorldEngine release does not yet provide an end-to-end workflow for this use case, so custom implementation would currently be required.

Thanks for your reply. I was wondering whether video-only data could be converted into SimEngine inputs, but I now understand the limitations.
