ociobakelut clamps tops?


Oliver Farkas <oliver...@...>
 

Hey guys,

I'm trying to use ociobakelut to bake out a .csp lut. I'm using the latest opencolorio (0.8.0), but getting weird results. It clamps the tops, details in the bright areas are completely gone. I'm wondering if I'm missing something.


The command I'm using is this:

ociobakelut --iconfig ./config.ocio --inputspace scene_grey18 --outputspace Dreamcolor --format cinespace > ./Kodak2383CoolGrade_ocio_Dreamcolor.csp 

The corresponding parts in the config.ocio look like this:


  - !<ColorSpace>
    name: scene_grey18
    family: lin
    bitdepth: 32f
    isdata: false
    gpuallocation: lg2
    gpumin: -15
    gpumax: 6


  - !<ColorSpace>
    name: Dreamcolor
    family: lin
    bitdepth: 32f
    isdata: false
    gpuallocation: uniform
    gpumin: 0
    gpumax: 1
    from_reference: !<GroupTransform>
      children:
         - !<CDLTransform> {slope: [0.80369623146242275, 0.9566818354009814, 0.94751600781483858], offset: [0, 0, 0], power: [1, 1, 1], saturation: 1}
         - !<FileTransform> {src: jp_lin2log.lut, interpolation: linear}
         - !<FileTransform> {src: Kodak2383_Dreamcolor.cub, interpolation: linear}



Cheers,
