"color_space" parameter is not exported to ass

When you exported a shader graph including aiImage nodes to an ass file from "Export Selected Shaders" command,

the ass would have no "color_space" parameter regardless of changing the default value.
This is obsolutely a bug.

 

My environment is MtoA5.4.2.1 on Maya2024.2.

Case1: Arnold > Scene Export > Export Selection to .ASS

image

color_space "sRGB"
filter "closest"
multiply 0.314999998 0.314999998 0.314999998
offset 0.5 0.5 0.5
missing_texture_color 0 0 0 1
}

In case 1, you're also exporting a color manager node, right? 

MtoA does not export image.color_space if there's no color manager. I guess that's a bug, or it was a design decision.

Yes.I exported a color manager node as well.
I noticed the following about "Export Selection to .ASS".
If  I turned off "Color Manager" in the options dialog and then pressed "Export Selection",
"Color Manager" option in the next file dialog was turned on again.

I figured out that MtoA didn't export color space parameter when a color manager node was not exported.
But this specification was not good for me because a definition in a shader graph was not able  to be exactly represented.
