Hi,
To get a better idea of the issue, could you provide some more information on how your TArray<FVector> is set up and used?
In my own test project, I did observe the elements of my TArray<FVector> all using the FVectorNetSerializer, rather than one of the serializers derived FPackedVectorNetSerializerBase. However, without Iris enabled, the elements of this array still seem to use standard vector serialization without any quantization, and I’m not seeing them call into the quantized types’ NetSerialize functions.
Thanks,
Alex
