Hello,

I want change my mplay's setup per project.


My first approach was by using Environment variables and Mplay Profiles.

I set up environment variable from Houdini's Variables menu.

$GAMMA == 1
$LUT == /path/to/lut

Then Inside of Mplay Profiles Windows, change Cammandline Option to “-K -T -R -G $GAMMA -d $LUT”

Weird thing is, lut option work well with $LUT but gamma option does not work with $GAMMA. So it does not set 1 to gamma.

If anyone know how to resolve this, please let me know.


I also want to listen another way of doing project basis mplay setup.

Thanks in advance.

If you export HOUDINI_IMAGE_DISPLAY_LUT and HOUDINI_IMAGE_DISPLAY_GAMMA, they should be picked up both by mplay and houdini sessions. If you want the settings to override the stored settings in a hip file you can use HOUDINI_IMAGE_DISPLAY_OVERRIDE to do so. As for ‘per project’, you need a way to control the environment per project.

Hi, jsmack. Thank you for the answer.

Unfortunately, it didn't work for me. Don't know why.

I am using Edit - Color Setting for lut, but it also doesn't handle gamma.
