Issue Overview

Some of the models from Wildlife Park 3 have issues with being imported over, which seems to be from the geometry. The importing of skeleton works as it is but the geometry does not. The meshes/geometries, except the base model mesh, along with skin weight are not imported over. The intended result is suppose to have the "editable poly" inside of the "scene root" already. (This applies to the base game only, DLCs have yet to be examined)

Version Information

Blender Niftools Addon Version Info

0.0.13

Blender Version Info

3.0.0

Platform information

Windows 11 (64-bit)

Context

Warning error log produced when imported Several missing geometries, including skin weight

Steps to Reproduce

• Import a specific vanilla animal mesh from Wildlife Park 3 (base game)
• A warning log will be produced when importing

List of files that produces the error: puma.nif and grizzlybearbaby.nif

Expected Result

A successful import without any error logs, "editable poly" and other geometries with skin weight are inside/a child of "scene root".

Actual Result

An error appears when imported, causing some of the geometries along with the skin weight to be missed out. "Editable poly" is not within the "scene root".

Possible Fix

Screenshot

Here are the missing "geometries" I'm talking about, model in .obj exported and imported to blender:

Additional Information

[HENDRIX-ZT2]

It's an encoding issue - the string names contain German 'umlaut' characters ä, ö, ü etc, but not in the expected UTF8 encoding. Instead they appear to use ISO/IEC 8859-1 aka Latin-1 OR windows-1252. lionMlä#

[diszxchat]

Ah, thank you. That solves half of the issue. This wouldn't be applicable to the other model (baby grizzly bear), correct? The other model has more than 8UV Maps (the limit), from what the error is trying to say. Any ways to bypass it or limit the number of UV maps?

That is going to be a limitation of our format description/file reading library. The guys are working on an overhaul for it atm.
