Maya Model's Rig Configuration breaks after upgrading project from 2018.3 to 2019.1 or 2019.2

Asset Importers


How to reproduce:
1. Open the attached "" project
2. Click on the Models > Hoodie > "" in the Project WIndow
3. Observe Import Settings > Rig > Import Messages in the Inspector
4. Open the Import Settings > Rig > Configuration
5. Observe the Scene View

Expected behavior: The Rig does not change after upgrading a project
Actual behavior: The Rig Configuration brakes, bone positions are altered

Reproducible with: 2019.1.0a14, 2019.1.0b4, 2019.2.0a6
Not reproducible with: 2018.3.7f1, 2019.1.0a13

Note: .fbx files are not affected. The behavior is also reproducible when Importing .ma files from project saved in 2018.3 manually. The workaround would be to set Import Settings > Animation > "None" (or any other) and then set it back to "Humanoid".

  1. Response avatar

    Resolution Note:

    Unfortunately, we won't be able to solve this issue. The problem is that the avatar scale value was not saved before 2019.1. Therefore when changing the importer scale factor, the importer cannot take the previous scale value into account and assumes the previous scale is equal to the current scale factor. The only way to solve this situation is to reset the avatar ( by setting rig type to 'none' then back to 'humanoid').
    Note that the issue only occurs when upgrading to 2019.1 and does not occur when upgrading from 2019.1 to a later version.
