Maya 2018.4 crashes when calling MLL export plugin.

[Anonymous]

We have a maya exporter (a .mll plugin that has a subclass of MPxFileTranslator) that we've been using for some time.  After a recent update (to Maya 2018.4 I believe) I'm getting the following behavior:

1) The exporter loads successfully.

2) When I try to export the maya file maya hits an exception before every calling my MPxFileTranslator::writer function and consequently never calls my writer function.

Is this a known issue?  I have rebuilt the plugin thinking that maybe I just needed to link in new libraries but that doesn't seem to have fixed it.  Any support would be helpful.

I'm having the same issue here. No hard crash for us, just a non-responsive call, however we did not recompile our exporter for 2018.4. The plugin itself did load into maya, but did not work.

Rollback is a pain, you cannot uninstall the update even with the methods described on this forum. It required a full uninstall to get back to a working version; 2018.2

I was under the impression from Autodesk sales staff that Autodesk were embarking on a new way of updating their software that would not require re-compiles of plugins for ANY updates. At least that's what I was told in our recent meetings.

As a follow up: I was able to resolve this issue by making a copy of the Autodesk sample plugin for rawexport and then merging our code into that project while deleting the sample code. I never really determined what was causing the issue, but I suspect it was either a project setting or an older lib we were linking into our project that we no longer needed.

I was running into the same issue trying to build a plugin for 2019.2. It turned out that we needed to enable the "/GR" compile flag for run time type information.
