[11.0.0^] Point light has weird light texture source

I just tried to update 2021.1.2f1, I see that URP goes from 10.4.0 to 11.0.0 and I got some weird point light bug that seems like does sprite light.

Left : 10.4.0
Right : 11.0.0

This also cannot reproduce at vanilla, I'll report it with Unity bug report later (last one too).
Is anyone had like this problem?

 

I have got reply from bug report.
Support says it's cause deprecated light cookie field of point light contains sprite.

I tried to fix it myself, so here's I did automated macro to remove sprites from these field in point type 2D lights.

Gist : https://gist.github.com/Creta5164/92af723389a2867a814eb1c31a53e884

Code (CSharp):

1. using System.Linq;
2. using UnityEditor;
3. using UnityEngine;
4. using UnityEngine.Experimental.Rendering.Universal;
5.  
6. public static class RefactorCookies {
7.  
8.     [MenuItem("Tools/RefactorAllCookies")]
9.     public static void RefactorAll() {
10.      
11.         var allLights = GameObject.FindObjectsOfType<Light2D>();
12.         Debug.Log($"Gathered {allLights.Length} lights.");
13.      
14.         var pointLights = allLights.Where(component => component.lightType == Light2D.LightType.Point)
15.             .Select(light => new SerializedObject(light))
16.             .ToList();
17.      
18.         Debug.Log($"Gathered {pointLights.Count} point lights.");
19.      
20.         int fixedCount = 0;
21.      
22.         foreach (var lightCookie in pointLights) {
23.          
24.             lightCookie.Update();
25.          
26.             if (lightCookie.FindProperty("m_DeprecatedPointLightCookieSprite") is SerializedProperty depLightCookieProp) {
27.              
28.                 if (depLightCookieProp.objectReferenceValue) {
29.                  
30.                     depLightCookieProp.objectReferenceValue = null;
31.                     fixedCount++;
32.                 }
33.             }
34.          
35.             lightCookie.ApplyModifiedProperties();
36.         }
37.      
38.         //Based on : https://twitter.com/AdaRoseCannon/status/1380881598409740292
39.         Debug.Log($"Query OK, {fixedCount} Light2Ds affected.");
40.     }
41. }

 

Also, you can fix it manually.
Enable Debug view in Inspector and find Deprecated Point Light Cookie field and remove sprite value to solve it.
