2D Prefab not being reactive to light

Questions & Answers
1

I need your help.

  • I have sprite background and circle
    shaped sprite prefab.
  • I created
    Sprites/Diffuse material and attached
    it to them (for darkness effect).
  • I added point light source and “darkness” over background reacts to it.
    • When i drag prefab to game scene it also reacts to light.

But when I Instantiate prefab it is completely dark and not reactive.
I have checked all position.z values and sorting layers/order for prefab with no luck.

This is my first question here, please be nice. I am not intending to use URP.
Let me know how can i specify my question.

I found my mistake. After Instatiate i set localScale of prefab to Vector2. There is no diffrence in shape between Vector2 and Vector3, but Vector2 makes diffuse material g rogue.
