Regression

No

The model does not follow the aim when Rig is enabled

Package: Animation Rigging

-

To reproduce:
1. Open the project “Test”
2. Enter Play mode
3. Toggle “Enable Rig” on
4. Move the Slider to any extremum

Expected result: The model follows the sphere (aim) always when Rig is enabled
Actual result: The model follows the sphere (aim) only when the Slider is in the middle

Reproducible with: 1.1.1 (2020.3.37f1, 2021.3.6f1, 2022.1.10f1), 1.2.0 (2022.2.0b1, 2023.1.0a2)

Reproduced on: macOS Monterey 12.4 (Intel)

Notes:
- Doubled negative rotation of the root animation rotation is added when using 2 or more rotation-kind constraints
- The sphere object (aim) is at Model → Rig 1 → aim

  1. Resolution Note:

    After investigating this issue, we have found out that the aim constraint is evaluated before a rotation constraint. When evaluated, the rotation constraint will move the torso causing the aim to change.

    To fix this, just reorder the aim constraint and the rotation constraint in the game object hierarchy. Refer to this section in the documentation for more details:
