Some tangents return NaN when the Tangents calculation method is set to Mikktspace
Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. In the Hierarchy Window select “1” Game Object
4. In the Inspector Window right-click the “Check for Na N Tangents (Script)” Component and select “Check for Tangents NaNs"
5. Observe the Console Window
Expected result: Tangents were calculated correctly and no LogErrors are thrown
Actual result: Tangents were calculated incorrectly and multiple “Tangent 26912 is NaN” LogErrors are thrown
Reproducible with: 2020.3.48f1, 2021.3.25f1, 2022.2.19f1, 2023.1.0b16, 2023.2.0a14
Note: The reproduction does not occur with other tangent calculation methods
