Context:
I’m working in a plugin to add metadata to static meshes. For this, I have created a blutility to read asset metadata and assign a created subclass of AssetUserData to the meshes.
Problem:
Everything works fine, but when I save the project and close it, information disappears from modified static meshes.
Blutility:
Before Blutility:
After Blutility:
After re-open project:
bool UMODUtilities::SetAssetUserData(UObject * Object, UMODUserData* MODUserData)
{
if (Object)
{
}
else
{
UE_LOG(LogTemp, Error, TEXT("SetAssetUserData failed: Object is null."));
return false;
}
UMODUserData* newMODUserData = NewObject<UMODUserData>();
if (MODUserData)
{
newMODUserData->MODData = MODUserData->MODData;
}
else
{
UE_LOG(LogTemp, Error, TEXT("SetAssetUserData failed: MODUserData is null."));
}
//Test if Object is a mesh
if (UStaticMesh* inMesh = Cast<UStaticMesh>(Object))
{
inMesh->AddAssetUserData(newMODUserData);
return true;
}
else if (UMaterialInterface* inMaterial = Cast<UMaterialInterface>(Object))
{
inMaterial->AddAssetUserData(newMODUserData);
return true;
}
UE_LOG(LogTemp, Error, TEXT("FBXMetadataToMODData failed: Object isn't mesh nor material."));
return false;
}
Additional information:
I have try to add Transactions to the function but doesn’t change anything.
