i have create a VDBFromMayaFluid not, input the name of the fluid.  hooked it up to the VDBWrite node and export the vdb's
im reading these VDB's into a renderman vdb visualizer.  all seems to work except it seems the write node isnt writting the color information.   its checked in the VDBFromMayaFluid node along with others like temperature.  and they all come thru, but not color.  

any clues why?

i can send a scene

all channels (density,temperature,velocity,color,and so on) are exported only if they have a mode
Static Grid or Dynamic Grid.
