Question Component at index 2 could not be loaded when loading game object 'MainCamera'. Removing it!

How do I solve this error?

 

Did you ever figure this out? I've been having the same issue since I updated my project to the latest version of Unity.

 

Disregard my question, I just resolved it... In my case I just had to remove the "Flare Layer" component that was attached to the main camera of all of my scenes.

 

This happened when I was importing an asset...

 

Maybe too late but I solve this same problem installint unity 2018 lts

 

I deleted flare layer it isnt working tho

 

i have same problem

 

Had the same issue.
I think I found the answer here:
https://issuetracker.unity3d.com/is...ject-exception-is-thrown-on-opening-the-scene

Summarised solution:

Just before this warning in the console there is another warning:
Component GUI Layer in Main Camera for Scene Assets/SortingLayerExample.unity is no longer available.
It will be removed after you edit this GameObject and save the Scene.

Basically the Component type no longer exists and it will be removed next time the scene is saved.

 

I'm having the same issue with Unity 2019, anyone know how to solve this?

 

OMG This editor is so f... bugged even after 10 years not using it

 

Just delete folder which one is causing to error

 

can any body tell me in easy way to solve the error

 

Just click main camera and check the components in the inspector. For me there was a missing script.

 

im having this problem with some free assets i got from the store i dont know hoow to solve this issue

 

Sometimes assets include a demo scene. Open this demo scene and as shaneparsons already pointed out, simply delete the "Flare Layer" which is assigned to the "Main Camera".

 

No way to solve that F***ing problem.

how do you delete the flare layer I'm new

 

I actually just uncheck the flare Layer of the camera and works perfectly, but I don't know what the problem was

 

I had this problem with Standard Assets, but I noticed that it said it was for 1.8 version of unity, so it will not even work in the latest version!

 

I had the same problem. I solved it, with deleting a script in Assest\Standart Assets\Utilitiy\. The Script's name is in the Console. If you go back in the console, you should see an error at somewhere at the location above. You have to delete the script, where the error is, and then you should have no problems.

 

i have the same problem on unity 2020.3 pls help

 

I've deleted the camera and it comes up with the same error.

(Dont worry I found a solution)










Give up

 

What is solution pls help

 

I went to the code part and changed "public GUIText <coderdefinedname>" to "public Text <coderdefinedname>" after including "using unityEngine.UI" in header.
the code is at asset >standard assets>utility>simpleactivatormenu.cs

this helped in my case

 

Find the asset in the "Asset store", there you can see which version of unity is needed.

Error fix is easy! Here's how!
18 days ago
- Open Assets/StandardAssets/Utility/SimpleActivatorMenu.cs - change "GUIText" to "UnityEngine.UI.Text". (GUIText is officially removed in newer versions of Unity, but the package isn't maintained) - Press play on your scene to get rid of the remaining compile error warnings. - Enjoy! Serves as a great starting point for lots of different types of projects. Really digging it!

it worked great for me.

 

Thanks! This worked. So easy.

This one works!!!!!

 

it works! Thank you so much

 

This error (or its sister side effect of the component not being added, even though your editor code said it was) can occur for various reasons. I don't have standard assets in my project at all and the solution above about GUIText was of no use to me. I had an editor script that generated components on objects based upon what folder they were in. I was getting this error a lot, and I finally narrowed it down to the fact that unity didn't seem to be able to handle adding components to thousands of asset game objects in a single pass in the editor script.

Once I reduced it to work in passes of 300-1000 it seemed to do just fine. I had a max counter and if I hit that I stopped and logged a message that max was reached and to run it again. I didn't try above 1000 as it was enough for my needs to just hit it until it was done. If you have millions you may want to try a few more at a time.

Also, I was using the AddComponent(Type) method, but also tested adding a component with the direct generic AddComponent<MyClass>() and still had the issue.

 

me too.....

 

same

 

A bit off topic, but I landed here.
I had this error (no Maincamera, but colliders) on 2 Prefabs with Capsule Collider on a child object, while spawning them.
At the end I removed both capsule collider and added them again. Worked. (Probably corrupted somehow).

 

I wrote a script to remove all the GUILayers and the FlareLayers from all cameras.

BE CAREFUL WHAT YOU RUN THIS ON! BACK UP EVERYTHING FIRST!!!

Here's a more generic "do something to all scenes" one that doesn't do anything yet:

See comments in code for where you do the thing(s) you want to do to the scene(s).
