Regression

Yes

Prefabs are instantiated in the wrong position when dragging and dropping from Project window to Hierarchy

-

How to reproduce:
1. Create and open a new project
2. In the Hierarchy, right-click and select “3D GameObject → Cube”
3. Drag and drop the cube from the Hierarchy into the Project window to create a Prefab
4. In the Inspector, take note of the Prefab’s position
5. Move or rotate the Scene view camera slightly
6. Drag and drop the Prefab from the Project window to the Hierarchy window
7. In the Inspector and Scene view, observe the instantiated Prefab’s position

Expected result: The position of the instantiated Prefab is equal to the position shown in the Project window
Actual result: The position of the instantiated Prefab differs from the position shown in the Project window

Reproducible with: 6000.1.0b3, 6000.1.2f1, 6000.2.0a10
Not reproducible with: 2021.3.51f1, 2022.3.61f1 (e6a1f07378cd), 6000.0.48f1, 6000.1.0b2

Reproducible on: Windows 10 (by user), Windows 11
Not reproducible on: No other environments tested

Note: The Prefab is instantiated relative to the Scene view camera’s position/rotation, hence the need for step 5

  1. Resolution Note:

    Placement of objects in the scene has now been unified under the 3D Placement Rules preference. The expected behaviour described in this ticket was an unexpected side effect of the previous implementation.

    The implementation is working as designed, but we will log the complaint here as Product Feedback so this can be considered in any future placement work

    I am continually astounded at the bad UX decisions being made by Unity every day. Congratulations, you made Unity worse by design. Again.
    If there is a preference setting for this dumb behaviour, please tell us how to find it, rather than just saying "3D Placement Rules preference".
