I am doing a grading of a stereo project in the full Baselight and when I tried to export the LUT of one of the eyes I got an error ("Render failed: Unknown colour space a NULL"). It doesn't matter if I set the scene settings to be a single stack stereo or Left/Right eye on top. Also it doesn't matter if I have both tracks combined or not... Also If I have the stereo colour matching operator on the input layer or if I insert the operator under the input layer as a new layer. I tried to save the grade on the Gallery and applied this grade to a non-stereo project and of course this does not work. My steps: Set the scene as a stereo project with Left eye on top. I have two tracks, one of top of the other. I combine both eyes in a single stack and I did the "fix geometry" of one eye and after fixing the geometry I shot match one eye to the other one with the stereo color matching operator. Then when I apply a grade to one eye I have the same on both eyes. Everything is perfect but when I tried to export the LUT is not working. My colour journey is well setup and when I export the LUT my output colour space needs to be CGI linear/Rec 709 to send this LUT to the VFX guys (FLAME). In a non stereo scene the LUT export works fine. I am glad Mark Tucker is on this forum Please maybe someone can put some light here. Thanks!
