Now, we support 3D Demo scene ! Yeah ! 
3D Support is provided 3D Camera View Utility, which contain orbit, zoom, and pan.
Also finding the 3d hidden object model, be sure to check the documentation for 3D scene setup.
Enhancement for the 2D Camera View Script
In the Camera View 2D script attach on Level Manager,
we add an options to toggle infinite pan.
When you enable it, you can achieve the infinite pan effect just like hidden folks.
Btw, this is still in experiment, tell us more feedback to keep improve this.
Dynamic Add Hidden Object Options
We add an options to dynamic add hidden object at the runtime, here is how it use:
On the event you want to add hidden object, drag in the LevelManager, and call the AddHiddenObject Function.
Still, we fixed some bug and improve some minor code structure,
please ensure to backup the project before update.
If you found the material is not appear, probably you need to switch to the URP version.
