Reproduction steps:
1. Create a new project
2. Import the user-attached “ExportScene01_Text.fbx” file by dragging and dropping it to the Project window
3. Select it in the Project window
4. Ensure that the “Import Animated Custom Properties” option under the “Animation” tab in the Inspector is checked
5. Scroll to the bottom of the Inspector and click on the “Apply” button (if it is greyed out, skip this step)
6. Expand the imported FBX file in the Project window and select any of the 2 animations available
7. Inspect the animation in the Animation window and look for the property “my_prop”
Expected result: The property 'my_prop' exists and its curve can be seen
Actual result: The property 'my_prop' does not exist
Reproducible with: 2021.3.32f1, 2022.3.13f1, 2023.1.20f1, 2023.2.0f1, 2023.3.0a14
Reproduced on: Windows 11 Pro (22H2)
Not reproduced on: No other environment tested
Notes:
- To ensure that the FBX has the actual property data, open the fbx in any text editor (like VS Code or Notepad) and search for “my_prop”. If it is found, the property exists in the FBX but is not recognized by the Unity Editor
