Issue Overview

When importing a vanilla mesh file from Fallout: New Vegas, a warning occurs when importing the collision geometry. This same error message is then presented as an error when attempting to export the same file, causing the export to fail

Version Information

Blender Niftools Addon Version Info

0.0.13

Blender Version Info

3.0.0

Platform information

Windows 10 (64-bit)

Context

Warning produced on import
Error produced on export
As described above

Steps to Reproduce

1. Import a vanilla dungeon mesh from Fallout:New Vegas
2. An warning appears when importing
3. An error appears when exporting, causing it to fail

Here's my .blend after attempting the import

Expected Result

The file imports without error

Actual Result

An error appears when exporting, causing it to fail

Possible Fix

As discussed with a developer:

It looks like it's getting stuck on the part where it's setting the penetration depth of the imported collision. Mind you, that also means it wouldn't import anything past that.
And, of course, it prevents export.

Similar Known Issues

May be related to other issues with collision data. Not certain if any match exactly.

Additional Information

I've also tested with a Fallout 3 nif and got the same result. (I assume the shared assets are identical files)

Upon further testing, this issue appears to be specific to Blender 3.0.0

Thanks for investigating further.
Created some labels to start identifying there types of version/backwards compatibility issues as we have a few starting to crop up atm.
We have either had to revert things out as not supported by older versions and probably would want to put them back later once we drop older version support or for these type tickets where newer versions not being backwards compatible.

Fallout 4 support has nothing to do with this.

Oh, my bad. Sorry about that.

No worries, here is a discussion thread you can follow - #473
The two active devs are actively reworking our file library to support new versions into our format description which will ultimately lead to new game support.
