GameObjects not showing up

The day is April 6th, 2021... and I ran into this issue and found the simple solution thanks to a link to this question post. :D Turns out I did not have the layers set to default and that simple setting solved my issues. These questions and answers are awesome and good for a long time!

i have a 2d game object that does not show up while im playing the game but it does in scene. i have already tried everything in the comments but it still dosent show up. what should i do?

After upgrading to Unity 2018.3 I had some issues with graphics settings, but I figured out reading the unity blogs.

1. If your camera in your scene has 'Rendering path' setting to default, it might not show some of your prefabs or instances. Try changing it to see the objects rendered on screen.

2. It might be your graphics API selection on newer versions. Go to Project Settings -> Player -> other settings and uncheck Autographics to see what API you graphics unit might support. Just a play around is not enough. Read about it on the unity blogs before you choose API

if you're developing for XBOX with Unity 2018-3, visit here. https://blogs.unity3d.com/2018/12/2...6.1365772769.1546089470-1507696043.1524009639

if you're spawing it from a prefab, make sure is not disabled. Or that is veeeeeery small

this didn't help because in my case even though all my layers are visible I still can't see. but when I set the invisible object to "default" it becomes visible.... but in my editor I can't change that for some reason even though I have set it up as default in its prefab.
