Recap:

  • Livegrade:
    • @ptr showed the RGC in LiveGrade, it’s per “slot” or camera - and they persist in looks, similar to CDLs, etc
    • When you export an AMF, it will be included
    • Do we want to have it on by default for 1.3?
      • Possible to have a global preference
      • Group votes to yes, have it on by default, but able to turn off per clip via the checkbox
    • We need to move on getting the CTL updated and ACES URN updated for the ID
    • John Frith - checking that this is just for viewing and not baked into EXR/RAW media at this point?
  • User Guide:
    • Link to guide here
    • Asked for folks to generally look over and provide feedback
  • Other Implementation Discussion
    • @KevinJW - for OCIO 1.x, we don’t need an “official” solution yet, can use the Nuke implementation for now
    • Need the cut down RGC and post that on github with explicit documentation and hash link
    • The nuke version should have the inverse, should the resolve DCTL? Group agreed that it probably should for emergencies
    • Should we provide a “blessed” shaper/LUT implementation for OCIO 1.x? As it might be needed in RV/ other review applications where EXR / scene referred review is required
    • Could possibly ship a GLSL shader plugin made for RV

Todos:

  • Update CTL
    • Separate forward and inverse
    • Update naming
    • Update ACES URN / ID for AMF
    • Provide new naming to Patrick
  • Initiate conversation w/ Autodesk re: RV
  • Initiate conversation with Colorfront
  • Provide “blessed” RGC versions for: Nuke, Resolve, Baselight, RV (???)
