Datasmith scenario export not working propperly

Stefan_Harding — Wed, 13 Dec 2023 09:55:50 GMT

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.

Hi @Stefan_Harding,

Can you go a bit more into details?

What exactly is not working?
Creates a corrupted what?
What is greyed out?

Best,
Jonas

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.

Best
Jonas

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.

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.
