Bug PolybrushNullReferenceException

Hi I have just imported Polybrush 1.0.1 into my project UPT, Unity 2019.3.10f1 with Cinemachine package installed and I get:

Code (CSharp):

1. NullReferenceException: Object reference not set to an instance of an object
2. UnityEngine.Polybrush.OverlayRenderer.OnRenderObject () (at Library/PackageCache/com.unity.polybrush@1.0.1/Runtime/Scripts/MonoBehaviour/OverlayRenderer.cs:202)
3. UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

Which points to the:

Code (CSharp):

1. if((Camera.current.gameObject.hideFlags & SceneCameraHideFlags) != SceneCameraHideFlags || Camera.current.name != "SceneCamera" )
2.                 return;

and Camera.current when logged shows every nth time that it is null.

The only way i have found to prevent it was to delete whole if statement. The tool works but on every click it throws this error. Is this a bug?

Thanks!

 

I got the same exception in 2019.4.0f1 too.
My workaround is to add a null checking on Camera.current right before the problematic "if" statement.

if(Camera.current == null)
return;
if((Camera.current.gameObject.hideFlags & SceneCameraHideFlags) != SceneCameraHideFlags || Camera.current.name != "SceneCamera" )
return;

 

thanks！I have the same problem but i don't know how to solute...

 

for anyone who runs into this: with unity 2020.3.12f1 i noticed that the issue was only happening when i had the game panel undocked from the editor, for example on another monitor

when i placed the game panel back into the main window, the error stopped happening

 

My Solution
1. Copy PolyBrush Folder in .\Library\PackageCache\YourVersion
2. Delete PolyBrush in PackageManager
3. Copy Temp Folder to .\Packages
4. Fix OverlayRender.cs 202 line

if (Camera.current != null)
{
if ((Camera.current.gameObject.hideFlags & SceneCameraHideFlags) != SceneCameraHideFlags || Camera.current.name != "SceneCamera")
return;
}

 

Wow - docking to the main menu actually works, thanks for the tip

 

thanks, it's can works

 

Thanks

This was my fully solution:
I closed then replaced Game panel behind to Scene panel as a tab. Then i pressed start. Selected Game View and resolved.
