color_manager_syncolor is missing

Can you post an Arnold log (as an attachment) ?

That node ships with MtoA. It does have some dependencies, but they also ship with MtoA. Maybe reinstall?

I tried reinstalling Maya and then I installed the latest version of MtoA. No luck. Below are the errors im seeing. All sorts of issues with color management and texture conversion. If I disable color management all this goes away. But of course, we cant just do that.

Cheers

[mtoa.translator] synColorTranslator: Arnold node type color_manager_syncolor does not exist.

I needed to see the full log. I'm interested in what before the translation or the render.

Let's try it this way: open a Terminal and run this command:

/Applications/solidangle/mtoa/2017/bin/kick -nodes -l  /Applications/solidangle/mtoa/2017/shaders

Normally that should list color_manager_syncolor as one of the shader nodes.

Then run this

oTool -L /Applications/solidangle/mtoa/2017/shaders/synColor_shaders.dylib

Thanks for the response Stephen. I do see the shader available in the Arnold installation. When I run oTool, this is what I get.

What version of MtoA do you have?

Does this happen with any scene (like an empty scene) ?

Just to be sure, can you confirm that kick -nodes did list color_manager_syncolor ?

Can you get a startup log for MtoA? Open a terminal, and run these two commands:

export MTOA_STARTUP_LOG_VERBOSITY=2
/Applications/Autodesk/maya2017/Maya.app/Contents/MacOS/Maya

You can scroll up in the Terminal to select everything, and then paste it into a file, and attach that file to your reply.

Arnold is version 5.0.1.5
MtoA is version 2.0.2.4
It happens anytime I enable the color management setting in maya. Even with the simplests scenes.

The sycncolor node seems to be available

and here is the entire startup log of maya, per your suggestion

Thanks so much for your help.

The startup log looks ok.

When you render, there must be an error in the log about synColor_shaders.dylib. Normally, if verbosity is set to Warnings + Info, you would see this:

| synColor_shaders.dyloib: color_manager_syncolor uses Arnold 5.0.1.5

There must be something different in your render log. Can you check the Arnold log for a render (if you use the Arnold Render View, select View > Log > Full before you render) ?

The other thing I would do is this: open a terminal and run this command:

sudo dtruss -f -n Maya

Then go back to Maya and render a frame.

There will be a ton of stuff logged in the Terminal. Copy it all to a text file.

Finally, run this MEL command in the script editor:

system( "printenv" )

so we can check the environment.

sounds good. Ill dig into the logs to see whats up. Thanks for the guidance man.

Hi Stephen

I looked at my logs and I dont see a line where the syncColor_shaders.dyloib file is loaded. All other mtoa shaders seem to be loading.

I tried adding the shaders from arnold standalone to the ARNOLD_PLUGIN_PATH but the shader is not there either.

Please help. We are getting close to our delivery date and I really need to get this working.

Cheers and thanks for your help
