Hope someone came across this:
trying to use a deep exr generated in another package to hold out volumetrics rendered in Arnold.
Lacking a global option I was hoping to be able to read it into my shader (possibly through a similar shadow() call of the old Prman/Mantra trick or comparing Rl with deep samples) but so far no luck on even reading a deep exr.
Anyone came across this before?
Thanks,
Andras
