Unreal Engine 4.22 Preview

Yeah I am having the same issue with crashing maps. I’ve tried to track it down but there seems to be multiple things causing this corruption of a saved map file.
I have found that if I even edit (not even placed in the level) certain blueprint actors and then save the level it is corrupt next time I try to load it.
I have also had a material with a material function corrupt the saved level.

I have submitted the dump every time it has happened so hopefully they will have a chance to go over it.

Also I can’t even create a new blank blueprint project, I just get the error.

Missing MyProject422 Modules
The following modules are missing or built with a different version:

DatasmithCADImporter
DatasmithDataPrepEditor
DatasmithDataPrepLibraries
DatasmithVREDImporter
DatasmithDeltaGenImporter
DatasmithGLTFImporter
DatasmithFBXImporter
DatasmithImporter
StaticMeshEditorExtension
MeshProvessingLibrary
VariantManager

Would you like to rebuild them now?

And if I answer YES it fails to compile and says I should compile from source, if I answer NO it just goes away.

The only way I could fix it was to edit the .uproject file and change “Enterprise” to false (or remove it)
I wish if you created a new Blueprint Project (Not an Unreal Studio Project) it wouldn’t stuff Datasmith in there anyway.

Hi Kneebasher,

The issue should only be present when UE is in preview.
I agree that we should probably find a better way to let users know that they should update their plugin instead of this.
For the time being, Datasmith plugins must be updated and inline with the Engine.

You can update your plugin here :
