Maya 2022: MtoA - Ai Image color space drop down

[khaled.pamir]

I installed maya 2022 and im noticing that the color space menu is not showing up on ai image nodes anymore.

At work the AI Image node has this drop down.

This is a fresh install of maya, any way to bring this back?

Im including a screen grab as well.

Hi
Look under Extra Attributes, but missing the drop down list ! SolidAngle should correct this!
Open aiImage, under Extra Attributes /Notes
Copy/paste this transform and save it as preset, since the drop down list is missing, you have to manually type the space transform:
sRGB
ACEScg
ACEScct
ACES2065-1
scene-linear Rec.709-sRGB
Rec.1886 / Rec.709 video
scene-linear DCI-P3 D65
Gamma 2.2 / Rec.709
AdobeRGB
DCI-P3 D65
Raw
CIE-XYZ D65
ARRI LogC (v3-EI800) / AlexaWideGamut
RED Log3G10 / REDWideGamutRGB
Sony SLog3 / SGamut3
Log film scan (ADX10)

another way is by connecting Color Space from Maya File to aiImage/ ColorSpace like this:

but why?
why?
why are autodesk so dumb?

is it so hard to make a dropdown menu??

why it's missing? anybody don't use the aiImage node? I don't think so.

what kind of update is it when something is removed?

for what?

it's not logical at all!

Are we some kind of programmers?

No! we are just people, artists. make normal user friendly menus!

autodesk pieces of **** as usual!

Hi
Edit your config.ocio file located in  C:\Program Files\Autodesk\Maya2023\resources\OCIO-configs\Maya2022-default.
copy/past these lines:

file_rules:

- !<Rule> {name: curvature, colorspace: Raw, pattern: "*urvature*", extension: "*"}
- !<Rule> {name: occlusion, colorspace: Raw, pattern: "*cclusion*", extension: "*"}
- !<Rule> {name: ao, colorspace: Raw, pattern: "*ao*", extension: "*"}
- !<Rule> {name: ambientocclusion, colorspace: Raw, pattern: "*mbientocclusion*", extension: "*"}
- !<Rule> {name: opacity, colorspace: Raw, pattern: "*pacity*", extension: "*"}
- !<Rule> {name: mask, colorspace: Raw, pattern: "*mask*", extension: "*"}
- !<Rule> {name: roughness, colorspace: Raw, pattern: "*oughness*", extension: "*"}
- !<Rule> {name: glossiness, colorspace: Raw, pattern: "*lossiness*", extension: "*"}
- !<Rule> {name: specular, colorspace: Raw, pattern: "*pecular*", extension: "*"}
- !<Rule> {name: metalness, colorspace: Raw, pattern: "*etalness*", extension: "*"}
- !<Rule> {name: metallic, colorspace: Raw, pattern: "*etallic*", extension: "*"}
- !<Rule> {name: metal, colorspace: Raw, pattern: "*etal*", extension: "*"}
- !<Rule> {name: height, colorspace: Raw, pattern: "*eight*", extension: "*"}
- !<Rule> {name: displacement, colorspace: Raw, pattern: "*isplacement*", extension: "*"}
- !<Rule> {name: bump, colorspace: Raw, pattern: "*ump*", extension: "*"}
- !<Rule> {name: normal, colorspace: Raw, pattern: "*ormal*", extension: "*"}
- !<Rule> {name: basecolor, colorspace: sRGB, pattern: "*, *olor*", extension: "*"}
- !<Rule> {name: beauty, colorspace: sRGB, pattern: "*eauty*", extension: "*"}
- !<Rule> {name: diffuse, colorspace: sRGB, pattern: "*iffuse*", extension: "*"}
- !<Rule> {name: color, colorspace: sRGB, pattern: "*olor*", extension: "*"}
- !<Rule> {name: albedo, colorspace: sRGB, pattern: "*lbedo*", extension: "*"}
- !<Rule> {name: tx, colorspace: Raw, pattern: "*", extension: tx}
- !<Rule> {name: hdr, colorspace: scene-linear Rec.709-sRGB, pattern: "*", extension: hdr}
- !<Rule> {name: exr, colorspace: scene-linear Rec.709-sRGB, pattern: "*", extension: exr}
- !<Rule> {name: Default, colorspace: sRGB}

Delete any file like 13470907600626234644_filerules.txt in C:\Users\YOURNAME\Documents\maya\2023\prefs.
The conversion are done automatically based on naming convention for example:

albedo, color, beauty, diffuse are automatically set to SRB
bump, metalness, displacement, metalic, normal, metal, roughness etc.. are automatically set to RAW
tx, hdr, exr are set to scene-linear Rec.709-sRGB (you can set them to raw if you want)
Hope this help

This has been fixed in MtoA 5.1.1, see the release notes: https://docs.arnoldrenderer.com/display/A5AFMUG/5.1.1

• [MTOA-961] - colorspace missing from attribute editor in Maya 2022

This was due to a change in how the menu was created in Maya 2022 compared to Maya 2020.

Downloads are available from https://www.arnoldrenderer.com/download/

I was missing the color space drop down menu as well. After reading this thread I decided to download and manually install Arnold v5.1.1, but while that made the drop down menu available again it didn't allow me to change the color space to anything other than the default sRGB value, no matter what I did it would always revert back to sRGB as soon as I clicked away from the aiImage node.

I posted my issue here along with screenshots and as much information as I could gather, and in the end I ended up reinstalling Maya 2023 to revert back to Arnold v5.1.0 which has the color space field in Extra Attributes and I can at least change the value manually (seems to work... I think).

Anyway, I thought I should leave a message here as well, perhaps the people at Autodesk can shine some light into this issue?

It seems to be working fine for me in 5.1.1. Could it be Prefs related?

[cappellojuan]

Hey leegriggsGTKJS thanks for replying, I could give it another shot at manually updating the Arnold plugin to v5.1.1 and check.

Just to have a bit more info, how would I check or test if it is indeed Prefs related? Are there specific Arnold preferences I can just delete? Because before reinstalling Maya 2023 I did try going to the general settings and resetting them to default but that didn't fix it. I also tried the config.ocio edits that user Rachyd posted in the first page of this thread (plus deleting the filerules txt he mentions) but neither of those things fixed it either.

[cappellojuan]

Ok so I did a complete clean uninstall of Maya 2023, all the plugins that are also installed with it (like Bifrost, Substance, USD, Arnold, etc), and then manually deleted the remaining folders. Then rebooted and installed Maya 2023 without Arnold enabled during the installation process. I then installed Arnold v5.1.1 manually from the download link provided by ashley handscomb retallack a few messages above this one.

The color space field will just not work for me. I have no idea what's going on, as I am a student and I'm fairly new to Maya, but I can't figure out why it won't work while lee griggsGTKJS reported it works fine for him. Am I missing something here? The installation seems pretty straightforward, and as far as I can check everything seems to be installed correctly.
