The command I'm using is:
oiiotool /sim.exr --ch R,G,B --resize 50% --ociolook shotconfig -o sim.jpg
the known color spaces from oiiotool are
"linear", "sRGB", "Rec709"
That might point to the issue (the look I'm using has "AlexaV3LogC" as
the dst color space pre cdl in the look)
looks:
- !<Look>
name: shotconfig
process_space: linear
transform: !<GroupTransform>
children:
- !<ColorSpaceTransform> {src: Linear, dst: AlexaV3LogC}
- !<CDLTransform> {slope: [1.0002, 0.9439, 0.8126], offset:
[0.0065, 0.0001, 0.0238], power: [1.058, 1.0715, 1.0688], sat: 0.8}
- !<FileTransform> {src: sshore_logc_rec709_2-4.csp,
interpolation: linear}
The AlexaV3LogC color space is defined further down on the config.ocio
Cheers

Can you tell us the exact command line that resulted in the error?
Also, can you do a "oiiotool -" and tell us exactly what it says at
the bottom where it lists the possible color spaces?

Hi
I'm trying to use oiiotool to do some image conversions, based on
an ocio look defined in a config.ocio
The config checks OK (using sanityCheck from from the ocio python
module, or from the ociocheck application)
and when loaded to an ocioLookTransform in Nuke, it works fine
running the oiio tool with --ociolook lookname argument It fails
with this error..
ERROR: --ociolook (Could not construct the color transform)
any tips on what is expected by the oiiotool and missing in the
config?
