I don't have an OCIO environment set up. So I'd like to feed in a custom shaper lut file or simply copy and paste it in. Is there a command line way to feed a shaper lut file vs setting it in an OCIO environment? I don't think there is. I"ll send an example of what I've got tomorrow as I'm not currently in the office. It's just a matter of format in the shaper lut values.
I'm sure it would benefit me in the log run to set up the OCIO environment. One small thing is that we have a custom lin2log at our facility. Do you have a generic Houdini lut, with a lin2log in the pre lut, that you could share so I could look at the formatting?
