Maya 2020.2 and Release 0.3.0 (windows 10) - Plugin not loading

[brycelynch]

Clean install of Windows 10 Maya 2020.2 and maya-usd release version 0.3.0 fails to load plugin with following error:

The specified procedure could not be found.

Here is the output from console:

// Error: file: C:/Program Files/Autodesk/Maya2020/scripts/others/pluginWin.mel line 317: Unable to dynamically load : C:/Program Files/Autodesk/MayaUSD/Maya2020/0.3.0_202008140050-b9aab68/mayausd/MayaUSD/plugin/adsk/plugin/mayaUsdPlugin.mll

mod file located in autodesk shared common files appears to be mapped correctly to the plugin installation.

HI @brycelynch do you have any environment variables from previous builds of usd? the error you have is a generic plugin load error, but it isn't uncommon for environment variables (from old usd builds, or python paths, etc) to affect this.

[santosg87]

@brycelynch we have mayaUSD 0.4.0 available now, feel free to give a try on it and see if that loads as expected for you.

Cheers!

hi im also having this issue. Maya 2020.3 i tried versions 0.3.0 , 0.4.0 and 0.5.0 all resulted with this error

@DavidSpeicher Make sure that you don't have any versions of USD somewhere in your PATH. For instance the "Omniverse Connect plugin for Maya" will add USD to the path which conflicts with our plugin.

[DavidSpeicher]

this was my first time installing this plugin. so i dont think that would be the issue.

[santosg87]

@DavidSpeicher from the behavior you are describing, it does sounds like you might have something conflicting with the plugin.

I would recommend running the mel command
getenv "MAYA_MODULE_PATH"

and checking within the locations that maya returns to see if you have any "USD" or mayaUSD libraries/folders.

cheers!

FWIW. I converted this issue to a discussion. Once an issue is identified with repro steps, we can get it logged.

I would also look at the search paths and confirm that there is no other USD library in there:

import os
print(os.environ['PATH'])

Hi, I also have the same issue as @DavidSpeicher and @brycelynch. Installed Maya 2020.2, then installed release 0.5.0, opened Maya, tried to load the plugins, and ran into the same errors. Checked every single location in my PATH and MAYA_MODULE_PATH, there's nothing USD-related inside those locations except for the .mods that were automatically generated by the installer (there shouldn't be anything else anyway as this is the first time I install USD)

[seando-adsk]

I'm curious as to why you have your system python in "MAYA_MODULE_PATH"? Check your PATH and PYTHONPATH and make sure they don't have any references to your system python. You can check these from inside of Maya with the following commands.
getenv "PATH";
getenv "PYTHONPATH";

[DavidSpeicher]

version 0.6.0 im still unable to use this plugin at all. im also able to confirm this on 4 other computers with fresh windows and only maya 2020 installed.

Sorry can you run just the PATH one and post the result. When you run them together it doesn't output both.
