a bit of a pain when inspecting a particular item
Big +1 from my side
Hi, what particular items are being deselected? Is the most recent version used? Does this reproduce in an empty project?
any selected item
it happens on f1
doesn’t happen on an empty project so I reported a bug and attached the project #1204585
Probably a long shot, but are you using Addressables? There’s an issue where Addressables will do some weird stuff when entering play mode if you’re in “virtual” mode for addressables. The workaround is to use “fast” mode instead of “virtual” mode. But probably that’s not your issue.
no addressables and in term of packages, just this + amplify impostor

Thanks for the report @laurentlavigne . The devs are looking into it. Here’s the issue tracker link: Unity Issue Tracker - GameObjects lose selection when entering Play mode
Thanks, it was marked as sent to Allegorithmic …
Yep, workaround:
In the Project window go to “Assets” > “Allegorithmic” > “Plugins” > “Substance” > “Substance Engine” > “Editor” and delete “Substance.Editor Import Settings”
Works nicely!
sweet!
