Outputting A Float[4] As An Auxillary File

Recommended Posts

Hi everyone this my first post so bear with me,

I have a prman shader that is doing a multipass and can save an array of floats but the ribfile needs to have something like this in it:

DisplayChannel "varying float[4] arrayPass" 
 Display "+/arrayPass0001.exr" "openexr" "arrayPass" 

Anyway of doing this within one renderman output node in houdini in the aux section with the rest of my passes?

Using PRMan 13.0.2 (pro) and Houdini Master V8.2.13.

Hope that makes sense.
