Maya 2022 crash while loading Maya-Usd plugin #1503

NOTE: Apologies for the long message. I am trying to give as much info as possible. Maya crashes when I try to load the Maya-Usd plugin. Any help is much appreciated. Common build environment (for both USD and Maya-Usd):
To build USD 21.05:
To build Maya-Usd plugin:
USD was built using Pixar's build Python script. The build and installation went all fine. I can verify by running Maya-Usd was also built using Autodesk's build script and the build process ended fine. Here is the command:
I modified these options inside the I can run Maya just fine. This is the output in the console: When attempting to load the Maya-Usd plugin (the one I built), I get this error in Maya's Script Editor: Here is the crashLog (attached since it is quite large): And this is the full error message from the console after attempting to load the plugin: |

Hi Marcelo, Thank you for detailed information. It does actually help. Your build environments and arguments passed to Maya-Usd build.py looks good to me. Nitpick: You could also disable pixar and al plugins by passing them to build-args like how you did with BUILD_WITH_PYTHON_3
I would like to see what parameters you passed to Pixar USD build script? Did you build USD with Ptex?

hi Hamed, You are completely right about the CMake flags for building Pxr and AL plugins. I will clean my CMakeLists.txt and use the flags instead. Yes, I am building USD with almost all, including Ptex. Here is the call for the USD build script:
I know Maya ships with some of those libraries (Ptex, Alembic). I am not sure about OpenVDB, OIIO, OCIO and OpenSubdiv but I believe it does as well. Maybe I should build USD with the bare minimum. Example: |

This could be something new that we haven't seen before. I always build USD with everything under Imaging OFF which includes Ptex. I also believe that's how we build USD internally as well. python3 build_scripts/build_usd.py ${some_path_on_my_machine} Here is my USD build summary flags: Nitpick: I also believe passing -DPXR_USE_PYTHON_3=ON is redundant since you already running |

Hi Hamed, I re-built USD with the bare minimum. I also re-built Maya-Usd plugin against the new USD build. As soon as I unloaded the Arnold plugin in a fresh new scene, the plugin manager warned me that the scene was using the plugin and asked if I want to "force" the unload, which I did. Maya crashed. So, just to double sure, I ran Maya again, without any custom build or anything that could affect. Just Maya out of the installation directory. Tried to unload Arnold. Maya crashed. The following crash has nothing to do with Maya-Usd plugin. It is just trying to unloading Arnold. So, I am running into 2 issues. One that my custom build of Maya-Usd plugin is not loading... but trying to reduce the number of variables and unloading Arnold, causes Maya to crash. Now I am really puzzled. |

Hi Hamed, Before, I was not appending the custom USD build (bin) to the PATH. I thought the Maya-Usd runpath would take care of it. |

Hamed, what is also concerning me is that in another conversation, you mentioned that Maya does not ship with Pixar core USD libraries/includes/executables. It is true for Maya 2020, but for Maya 2022.0, it is there. The Maya installation setup created a sibling directory named (Yesterday, I installed Maya2020.4 to try build the plugin against it, so it is showing in the list below. But all the errors I have been mentioning are happening before, when I had Maya 2022 only) I believe the subdirectory Running Maya 2022, in the script editor, importing I am wondering if Arnold was built using the Usd that is shipped with Maya2022 and, when I try to provide another USD (the one I used to build the MayaUsd plugin myself), Arnold crashes. I could be completely wrong here. |

Hi Marcelo, Very interesting... I suggest taking baby steps to find the real culprit: First test: Second test: Third test: |

Hi Hamed, Sorry for the late answer. I was dealing with other tasks.
The difference was that my USD core build has only the minimum necessary for the MayaUsd plugin to build. Maybe it would be nice to add that information in the MayaUsd build steps page for other users. Thanks for the help and patience. I am flagging this discussion to be answered. Ps: Maya 2022.0 in Linux (CentOs-7 at least) still has a crash while unloading the Mtoa plugin. That was there from the first day. But that is another story all together. |

Hi Marcelo, No worries, glad to hear you passed the issue. We should investigate the issue your have reported with PTex. |
