Datasmith scenario export not working propperly

Question

As part of the project I'm working on i need to export city engine models in a verity of scenario to Unreal engine. But when I try and use the scenario export feature it either doesn't work, creates a corrupted or is greyed out. I have tried this with a fresh document and it had the same issues.

thanks for providing the project. It could reproduce it on my side, it seems there is an issue with the scene file itself. When I created a new scene file and imported everything from existing one, I can again use the scenario settings.

We will investigate this further but this might take some time, in the meantime I hope you can make use of the workaround described above.

I used 2023.0 for some earlier tests that gave corrupted datasmith exports, for the newer one I updated to 2023.1 and the scenario options that you show here grey out after one export and continue to be unselectable. Her is a download to one of the project's with greyed out scenario options:

I have gotten a brand new project to work without issues, but i have no idea why.

What version of CE/Unreal are you working with?

In general: If you select a scenario to export the selection has no effect on it. All objects of a selected scenario are exported

The different scenarios should be available for selection/deselection as soon as the you check the general "Export Scenarios" option

If this is not a case this might be a bug.

To further investigate (if you still have the described issues) we would need you to share the CE project with us.
