Are MtoA 3.2.0 and Maya 2018.2 compatible?

[malcolm.vanaardt]

Good day,

I am strugling to get the new MtoA 3.2.0 to work in Maya 2018.2.

I have downloaded and installed the latest MtoA 3.2.0, on a network, from here https://www.arnoldrenderer.com/arnold/download/ selecting the windows, Maya 2018 option. Once I am in Maya I am unable to load the plug-in. It looks like this :

and returns this error: # is the server

// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: Unable to dynamically load : //#/pipeline/DCC_Tools/common_binaries/Arnold/mtoa/2018_3.2/plug-ins/mtoa.mll The specified procedure could not be found. // // Error: file: C:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 290: The specified procedure could not be found. (mtoa) //

I have setup the .mod file: # is the server

+ MAYAVERSION:2018 PLATFORM:win64 mtoa any \\#\pipeline\DCC_Tools\common_binaries\Arnold\mtoa\2018_3.2
PATH +:= bin
MAYA_RENDER_DESC_PATH += \\#\pipeline\DCC_Tools\common_binaries\Arnold\mtoa\2018_3.2;

This is how I have set up every other version of MtoA that we have deployed on our network the last working one being MtoA 3.1.2.1

Any help will be appreciated.

None of the Maya 2018 updates break binary compatibility (I didn't see anything in the release notes).

• Check your environment by running system("set")
  In particular, look for anything in PATH that points to a different Arnold.
• Run Process Monitor and check what happens after mtoa.mll is loaded

Thanks for the response. I used the Process Monitor and found that our conflict was coming from the lightshader.v.0.2 that we are using.
