By the way, there's code below here for putting curves into "Location", "Scale", etc. groups, but since it only runs if grpname is false-ish, I don't think it will ever run.

Scurest (scurest) added a comment to T77059: Error collada import about negative numbers (source file does not have negative numbers for materials).

The IOR message is harmless. OpenCollada's getFloatValue() defaults to -1 when a float parameter is missing, so a file without an <index_of_refraction> is indistinguishable from a file with <index_of_refraction><float>-1</float><index_of_refraction>. That's why it thinks there's a negative value.

Leaving this since master has progressed far ahead of this patch and the exporter is moving to C++. This code had unfinished business as the subsurface extension is not implemented to replace the troublesome transmission vs. subsurface hack and file paths with spaces don't raise warnings about compatibility issues.

A bit sad to see this issue being dragged through the Blender versions (up to 2.92.0 now) way back from 2.79.
Maybe this addon should be removed from the default installation if there is no interest/no resources available to make it work with the version it is being included in? As it stands I find it a bit misleading to see the possibility to export into the X3D format from a fresh Blender install not knowing that this addon has been broken given the lack of support for materials since it last worked in 2.79 (2017).

Just spit-balling here (First time trying to help debug something, feel free to tell me to tell me I am wrong) I am looking in the python files the Blender distribution comes with, I see that the numpy version.py file is calling it out as version 1.17.5, I just got done downloading numpy to try check it out and see if I could stumble across something, and when I downloaded it, I got version 1.19.5. Is it possible it just needs the numpy updated? Possibly that all the Linux distributions are using an older numpy?

I don't think it's a python version thing, because as reported in T84752 it does not happen in the flatpak version, which, as far as I can see, uses the exact same python interpreter as snap and official build: Blender's Python console shows PYTHON INTERACTIVE CONSOLE 3.7.7 (default, Jul 9 2020, 12:52:49) [GCC 9.3.1 20200408 (Red Hat 9.3.1-2)] in all three versions.

@Scurest (scurest) That is an interesting find. We did have issues in the past where Linux distributions build Blender with an incompatible Python version, but those have been addressed (see T81688 and related tickets) and also produced a proper stack trace. Although I'm not entirely certain I was also under the impression that the snap package is maintained by us, thus should have the correct dependencies, but I would have to check. If this also happens with official builds as T84752 seems to report, a mismatching Python version doesn't appear to be the cause. You can check the currently running Python version by switching to the Scripting workspace and looking at the Python console. It should be 3.7.7 for 2.91, 2.92, 2.93.

You got it @Scurest (scurest) ! Hit the nail right on the head! Crashes the exact same way as exporting or enabling addons!

Can you open the Python Console and see if import numpy crashes Blender? Someone reported a similar issue on glTF-Blender-IO using Ubuntu 20.10. I see that Add Mesh: Extra Object imports numpy when enabled, and glTF imports numpy when you hit Export, so it'd be consistent.

I'm guessing there might be other features that cause a core dump, havn't found any yet.
I'd really like to help find a why to reproduce, but I have no idea where to look ...
