[SIMPLE] Sprites not showing in scene view?

I have an example scene taken from the asset store. If I import the scene in a brand new project evertyhing is fine.
Instead if I import the same package into another project of mine then are not visible.
Could you tell me why ? I dont think is a problem of sorting layer but something with graphics/openGL issues…

I had the same issue. If you are in 2d mode, change to 3D, select the “missing” object in the hierarchy and pan around in the scene view, because it is probably there, then increase (or decrease) the transform position z value, as much as you need (in my case up to 90), and voila!
Being a beginner myself I do not know the reason of this behaviour, but it works.
