I’m looking for some help on how to import and use a colour cube.
I’m getting a load error:
the application cannot load the colour transform file:
OpenColorIO error reading
< .cube>
The specified transform file
.cube
could not be loaded. Malformed color triples specified in Iridas.cube lut: 'LUT_3D_INPUT_RANGE 0.0000000000
Bit more info, it also won’t open in Nuke, but will open in Resolve.
You can put the file here for a closer look.
You can also re-export it from Resolve.
i’ve used .cube files many times in flame. it didn’t used to be able to read them but as of a few versions ago it’s possible. sounds like the flame is not the culprit here…
I think you’re right Tim. As I said, it works only in resolve, so I suspect the issue lies there.
We’re waiting to hear back from the clients, just means we can’t send them any QT’s
This is the header info:
#------------------------------------------NOTES----------------------------------------------------------------------------
#------------------------------------------FLOW-----------------------------------------------------------------------------
#------------------------------------------DATA-----------------------------------------------------------------------------
LUT_3D_SIZE 33
LUT_3D_INPUT_RANGE 0.0000000000 1.0000000000
What are the first and las lines of the cube values?
You can try getting rid the the “LUT_3D_INPUT_RANGE 0.0000000000 1.0000000000” line.
First line after output size should probably be an X Y Z value
First line:
0.043900 0.044134 0.044172
Last line:
0.784593 0.784593 0.784593
getting rid of the the “LUT_3D_INPUT_RANGE 0.0000000000 1.0000000000” line seems to have done it, I can now load it.
Clients have now sent an updated cube, with tweaked header which loads, and gives same result as my tweaked one.
