Trackback errors | Sim Update 5

[azgoodaz]

Blender not opening up models anymore? I've been on 2.83 Stable LTS of Blender for over a year now and never had issues opening models now. But I tried to open up a few aircraft models now and I just get Trackback errors now when opening up a model.

Traceback (most recent call last):
  File "C:\Users\Azgoodaz\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons\io_msfs_gltf.py", line 283, in execute
    return import_msfs_gltf(context, self.filepath, self.report)

Can someone with the latest MSFS update maybe veryify the issue? Would be deleting / just ignoring the missing scale node in this case just work? Unfortunately I have no MSFS subscription currently due to lack of time for this hobby and cannot investigate what has been changed in the latest update.

A non-developer fixed the issue. Maybe you can push this update? https://forums.flightsimulator.com/t/3d-livery-painting-on-the-msfs-models/257637/128

I can confirm the problem, and that the linked version fixes it :)

However, I notice the UV map for the prop on the 152 is massively out of scale - might this be related?

Since the issue seems to be caused by some missing scale node information that had been used before and now is simply ignored when they are "missing", this would explain the out of scale UV map in this case if it didn't happen before.

Maybe Microsoft / Asobo changed the file format as part of the optimizaion process or so? Unfortunately there's nothing really left from the Khronos glTF standard anymore in these MS / Asobo "glTF" files anyway.

I have the sim installed on a different drive than C if that matters?

Hey,
I want to do my own livery too but have the same problem. I just wanted to ask if you found the solution.
