Question GameObjects appearing in Editor but not in Build (disappearing) Problem.

Please take a lot at the pictures!

As you can see in the editor, I can see and control the player character, but in the build I can only move the player character, but I can't see it, also some other GameObjects Materials disappeared!
What could be causing this problem? And how to fix it? Thanks

 

Check the runtime logs. Google for where they are located on your machine.

You'd be looking for things like exceptions or errors in the log.

OR if this is just a UI Anchoring issue, here's some notes:

Here are some notes on UI Anchoring, Scaling, CanvasScaler, etc:

Usually you need to choose a suitable ScaleMode and MatchMode in the Canvas Scaler and stick with it 100%. Generally if you change those settings you will often need to redo your UI entirely.

I also use this

CanvasScalerOrientationDriver

utility to make sharing UI for Landscape / Portrait easier. Read what it does carefully.

Thank you for your suggestions, but If you take a look at the pictures, this is not an UI Issue, but some 3d objects and materials seems to disappear
