UE5 Crash after Datasmith import

Development Architectural and Design Visualization

I have just started trying to use UE5. When I import a file using datasmith the file appears in the viewport then UE5 crashes.

I have updated my graphics drivers to the latest

Hi DeeryD !

Can you give us a bit more context on your datasmith scene ?
What DCC is it coming from ? What version of the Datasmith plugin have you used in that DCC ?
What kind of crash (a log would be good) do you get when importing the file ?

Cheers,
Antoine

Hi Antonie

Thank you for your response. I’m exporting from Revit 2022. I am using the sample Revit model Simple Architectural Project. Version of Datasmith 5.0.1.0

No. I didn’t get a solution. I still can’t bring a Revit model into 5.0

I was regularly importing Revit models via Datasmith but since upgrading to UE5.1 they will not import. Actually, one of the models has loaded, the other 3 will not.

Make sure that if you need to convert the revit file, that you save the upgraded file BEFORE exporting through the Datasmith export function. It makes a difference.

Can you share with us the models that are failing to import? Do you get any errors in the console window?

Hi, I use Unreal Engine 5.44, and I do have the latest Cinema 4D 2025 with the latest plugin. However, the app keeps crashing when I import the After Effects 3D tracking data (exported as a C4D file). I managed to make it work before a few times, but it mostly crashes. The direct link seems to work fine from C4D to UE. Do you have any tips?
