how to correctly close deduplication

7

I try close deduplication by removing the definition DRACO_ATTRIBUTE_INDICES_DEDUPLICATION_SUPPORTED and DRACO_ATTRIBUTE_VALUES_DEDUPLICATION_SUPPORTED but I get bad compress result: I set qp - 11 qt - 10 qn -0 qg - 0...

When I close prediction, func EncodeValues in SequentialIntegerAttributeEncoder will go into func ConvertSignedIntsToSymbols. Then ConvertSignedIntsToSymbols will turn uint16 value like 63990 to 127980. Then the uint16 attr will be encoded...
