Have you made any change regarding dynamic loading of assets in 1.40?
My project works in 1.39.4 but in 1.40 when I jump between scenes some assets are not loaded properly.
Here’s a build I can share:
To see the issue:
-click on the glass behind the hiking couple to jump to the nature scene
-press B on your keyboard to jump back to the main hub
In 1.39.4, everything loads fine.
