there is a bug in the dvr lookup table code. Locally it initializes
everything correctly but does not mark it for transmission in the
cluster (dvrlookuptable::commonContructor). The easiest way for you
to work around this is to mark everything of the dvrluttable changed
in your makeVolume function, e.g.: change
beginEditCP(lut, DVRLookupTable::TouchedFieldMask);
lut->setTouched(true);
endEditCP(lut, DVRLookupTable::TouchedFieldMask);
// Initialize the lookup table
beginEditCP(lut, DVRLookupTable::DataFieldMask);
for (int i = 0; i < 1024; i++)
lut->getData()[i] = lutData[i];
endEditCP(lut, DVRLookupTable::DataFieldMask);
to
beginEditCP(lut);
lut->setTouched(true);
for (int i = 0; i < 1024; i++)
lut->getData()[i] = lutData[i];
endEditCP(lut);
with this change I can see the volume spinning on the server.
