maketx --colorconfig not converting correctly

Hello

I am trying to use maketx in the command line (Linux) to batch create my .tx files.

I am using an .ocio file within Maya and when I generate .tx from within Maya results are correct.

Using the --colorconfig flag with maketx (or oiiotool) is not working for me though. Disregarding other flags should my command just be:

maketx --colorconfig /path.../config.ocio /path.../file.jpg

The OCIO environment variable is not set system wide, but if I have the full path to it, that should be enough?


Also I have tried to unpick the command Maya uses when creating .tx from there and it uses

maketx /path.../file.jpg --colorconvert "Utility - sRGB - Texture" acescg 

When I do that from the command line I get an error 'Creating Color Processor' even after I set the OCIO variable within the shell.

Any thoughts anyone?

Thanks


Dave

If I take the command that Maya used, and add --colorconfig, that works for me.

Hi Stephen

I see...so --colorconfig and --colorconvert need to be used together.

Thanks for looking at this.
