PackagingResults: Error: Bad name index -1/47

Solution 1

You can find the asset causing this by building the engine from source and adding breakpoints in these two place:

LinkerLoad.cpp

void FLinkerLoad::BadNameIndexError(NAME_INDEX NameIndex)
{
    UE_LOG(LogLinker, Error, TEXT("Bad name index %i/%i"), NameIndex, NameMap.Num());
}

and

PackageReader.cpp

FArchive& FPackageReader::operator<<( FName& Name )
{
    check(Loader);

    NAME_INDEX NameIndex;
    FArchive& Ar = *this;
    Ar << NameIndex;

    if( !NameMap.IsValidIndex(NameIndex) )
    {
        UE_LOG(LogAssetRegistry, Fatal, TEXT("Bad name index %i/%i"), NameIndex, NameMap.Num() );
    }

    // if the name wasn't loaded (because it wasn't valid in this context)
    if (NameMap[NameIndex] == NAME_None)
    {
        int32 TempNumber;
        Ar << TempNumber;
        Name = NAME_None;
    }
    else
    {
        int32 Number;
        Ar << Number;
        // simply create the name from the NameMap's name and the serialized instance number
        Name = FName(NameMap[NameIndex], Number);
    }

    return *this;
}
