Greetings,
I believe that either the initial videos need to be updated OR another video needs to be inserted to address everything being white in Unity, take a look at the image.
I believe a good place would be before the initial “Experimenting” video. It might also be helpful, to go over more in-depth on rotating / panning / zooming / manual coordinates and what the units in Unity are. According to the manual a scale of 1, or 1 Unity unit, is equal to 1 meter.
To me, these are critical things that should be covered sooner rather than later.
BTW - this is a new install of Unity 2022.3.16.f1 on a clean install of Windows 10 Pro (22H2) with no customizations.
Cheers,
Noral
