What flag do I use to turn off color management?

[sfillat]

When I export .ass files from Maya I have to un-check the "Color Manager" flag to get my renders to run. I'm currently testing Thinkbox Deadline to control my renders and have to use command line arguments instead of the maya export GUI to turn off Color Manager and specify my plugin libraries path. Here's the flag I cam up with to disable Color Manager: "-d color_manager_syncolor" Is that what I should be using?

The renderer no long complains about not being able to find the color managment stuff, but it's giving me this error now:

[ass] line 36: options.color_manager: unresolved reference to 'defaultColorMgtGlobals'

which makes me think there's something else I need to do.

You need to export the ASS files without the color management. Otherwise, you need to use -l to provide the location of color_manager_syncolor

Thanks! What flag can I use to export ASS files without color managment?

[Stephen.Blair]

How do you export the ASS files now? With the arnoldExportAss command? By setting the Render Type to Export Ass?

[Stephen.Blair]

For arnoldExportAss, use mask=255

If you're setting the Render Type to Export ASS, then you can run this pre-render MEL script:

setAttr "defaultArnoldRenderOptions.output_ass_mask" 255;

Then everything except the color manager is exported to ASS.

Sorry, I should have been more explicit. I'm using kick to render. Is there a flag in kick I could use to do what you describe above?

[Stephen.Blair]

No, you can't do it with kick. Export flags have to be set in Maya. Once you have the color manager node in the ass file, you can disable the node, but you can't disable options.color_manager

You could do something like this:

kick with_color_manager.ass -d color_manager_syncolor -resave no_color_manager.ass

That would give you an ass file with the color manager node and without the options.color_manager parameter (at least it did in my quick test)

Thanks so much!

Hello to everybody! Why I cannot find any setting in Arnold for disabling color management export? I can see that option in File->Export all.. (in ASS export untick "Color management" field). But when I use Render type "ASS export" in arnold settings there is no similar tick to untick color management. Why? So I should go on the internet and have a long googling about this issue? What about usability?

thanks to Stephen Blair for pre-render script though, it worked for me
