Blend File

Here is a simple blend file with only a box with mesh collision, try to export to reproduce problem. New Compressed (zipped) Folder.zip

Nif File

This Can be recreated with any nif file with a mopp, but here is a nif file I made with blender 2.78c and a nif plugin from Jan 9, 2019, as the current plugin does not export but this does. New Compressed (zipped) Folder.zip Just Import then export to see what I mean.

Additional Information

[Anything else you feel is relevant]

Ok, So this is my first time using github, but this issue has been racking my mind as I found a partial solution. I was recently using the newest commit from github and tried to export a nif file with mopp collision, and it gave me an error. so I tried to look in the code to fix it, and I got a little ways by replacing * with @ at lines 524, 531, and 534 in the (io_scene_nif/modules/nif_export/collision/havok.py). But now I am getting the errors:

Weird thing is that it imports just fine, but I am not sure if I should have said this here.

Can you fill out the sections of the template as it enable us to reproduce the issue, thanks.

[JimScript]

Again, I apologize, I am using blender 2.83 with the nif plug-in from roughly 14 days ago on Windows 10 Home 1903, and this particularly only happens when the collision is set to "mesh". Changing the lines I listed shifts the problem forward but it still does not export. Other collision types still export just fine(Well there are a few inconsistencies, but they still export). Again, I am new to this, please ask me more if you need more. All I am doing is importing nv_westjuniper03.nf From new vegas, the exporting it to test out how to export terrain.

[neomonkeus]

Yeah, can you update the issue with all of the above, including providing attaching the nif in question.

[neomonkeus]

This requires some updates to PyFFI in order to resolve the underlying problem.

Looks to be the same issue as https://github.com/niftools/blender_niftools_addon/issues/453.

[Allofich]

This is fixed in newer code.
