    Hi everyone,

    It’s time for an update from the Scene Management team and the work we have been doing on Prefabs. During the last few releases, and after fixing a large number of bugs you’ve reported (thank you!), we’ve made several improvements to the Prefab system.

    Our article What’s new for Prefabs in 2022.2? will show the improvements introduced in 2022.2 and how these updates can benefit you.

    In this article, we'll be covering:
    • Replace Prefab Asset for Prefab instance
    • Reorder added GameObjects and components
    • Delete GameObjects from Prefab instances
    • Explore improved override tooling
    Many of the new features have been requested by you and we hope they will be welcome additions to the existing Prefab workflows.

    Questions, comments, and suggestions are all welcome.

    Thanks a lot, those are really amazing helpful additions :)

    Can you say something about another long-awaited feature: Prefab Exposed Properties. So we can disable any override and allow overriding only some explicitly marked properties from prefab hierarchy and show all of them in prefab root inspector?

    Hi Jes,
    I hate to be the bearer of bad news: we have worked on a prototype for encapsulation and exposed properties but have decided to shelf it for the time being due to new priorities. That said, the idea is not abandoned.

    Unity continues to follow the path of replacing popular plugins with built-in tools. Thank you

    Really good we finally have an option to replace a prefab instance. I've always had to make a custom tool for this for no good reason. Being able to see inheritance tree for variants? Great! Next step: adding a dependency tree tool for viewing all asset relationships.

    Good improvements, thanks!

    Am I the only one having trouble watching blog post videos that hosted in Untity's own server?

    For years we had problems with inserting a new prefab in the middle of prefabs variants inheritance chain.
    Was this issue addressed ?

    I have no need for exposed properties, but some form of locking in the scene view would be incredible. The number of times someone on the team accidentally adds an override to a prefab is incredibly high. One of our biggest sources of level design bugs.

    First of all, this is a great update. But also, I noticed the blog post mentions "major refactoring of the Undo system". My latest 2022.1 editor crashes nowadays daily deep in some undo internals randomly. Didn't use to do that before jumping to 2022.1. So if at all related, I really hope you can devote some serious time now to get the undo bugs worked out too. There's been way too many lately. I can't really make a reliable bug report of this as it's so random, but here's some example stack traces under spoiler tags. (There's also the undo bugs ones already in the issue system, like undo getting child ordering wrong etc. which need a lot of love.)

    +1 this - it's super important, and becomes more and more so as the team and project sizes scale. Not to mention how useful it would be in UI as well.

    The other changes are great too, but "locking a prefab to prevent overrides" is one of the biggest pain points I found.

    Can we change a prefab parent?

    Not being able to modify the hierarchy after making it really makes iterating impossible.

    Great update!

    It would be nice to have the option to allow prefab replacements to match the scale of the objects.

    Hello.

    Am I the only one who finds the position of the main buttons very strange and inconvenient?

    I think the popularity of buttons has this order: Open > Select > Overrides. Also most of the time we have inspector window on the right side of the screen so for the most used operation (Open) I need to move the cursor very far and pixel hunting button.

    Original

    What I suggest

    Hi @Stardog

    Could you provide some detail for the option to allow prefab replacements to match the scale of the objects?
    A scenario in which you'd use it and how the UI might best support it would be super helpful.

    Thanks.

    Hi Andrew. Thanks for the feedback. You have a point, but here's why we went with the current layout:

    - In Unity, all the 'Open' buttons for assets are in the lower right of the inspector header. So keeping it consistent is a goal.
    - This button acts essentially as a CTA (call to action). The standard place for those are in the bottom right.
    - The parts of the screen that are easiest to reach follow Fitts' law. The points on the screen that are easiest to hit are, counter intuitively, in the corners. Of course this open button is not exactly in the screen corner though.

    Keep in mind that this open button here is not the only way to open a prefab for editing - you can also click the chevron on the Hierarchy, among other ways.

    But here's what I think we could & should do: I think what many users would like, is a way to do many operations, such as opening a Prefab and other things, directly in the Scene window. Without announcing anything just yet, I think you might see that happening, and when that is true, the amount of cursor movement needed to open a given Prefab will be smaller than ever.

    Thanks for the feedback. I understand your logic but I think that the open button is an old design decision that needs to be replaced with a solution for this time. Perhaps when this button appeared, there were no thoughts about a new prefab system.
    I click the Open button (the lower right of the inspector header) only few times for 6 years of work in Unity.
    Will be interest to have some analytic for this button.

    I hope in the future Unity team adds an option to change buttons positions for comfort using prefabs from Inspector people like me.

    Have a nice day :)

    Yes. I can't see a problem with it. I actually use just the Override option, I like it close.

    Hi, I am late to the discussion.

    Can anyone please suggest a plugin for the "Prefab Replace" feature?

    I tested with Unity 2022.3 LTS. There is a native replacing mechanics.

    I didn't remember exactly how I did it, But I guess I opened the target prefab and replaced the root of the prefab using a new prefab...

    Hi, our project is on 2020.3.30f1 and we have prefabs/variants like the following:
    Original Prefab
    -Child1
    -Child2
    -Child3

    Prefab variant
    -Child1
    -Child2
    -AddedChild
    -Child3

    Upon upgrading to 2022.3.10f1 the prefab variant becomes this:

    Prefab Variant
    -Child1
    -Child2
    -Child3
    -AddedChild

    Capture.PNG

    Looking at the prefab file in the updated version I noticed if I move around the children of the prefab variant, a block of code is added that determines the item's position (insertIndex).
    Capture.PNG

    Because this block of code didn't exist in previous versions, upon update it seems objects added to prefab variants default to being the last in the hierarchy. Also, I noticed the "insertIndex" parameter seems to take priority over m_RootOrder.
    This is a problem because the rendering order of the objects matter for our project. Is there any way to avoid added objects defaulting to the last position? Going through the project to find all instances of prefab variants and prefab variants within other prefab variants etc. will be very time consuming and inefficient. Any help would be very much appreciated!

    They updated prefabs at some point to support reordering children. Maybe it only moves to last when converting your older prefabs.

    Thank you for the response. I realize that the update to prefabs is what's causing this to happen, but I wanted to know if there was a way to fix this, or prevent this from happening in the first place.
