This is expected. The Mask Light2D mode is replaced by the CanvasItem Clip Children property, which makes clipping more convenient to perform. (The CanvasGroup node may also be relevant to your needs, depending on what you need to achieve.)

but if i want mask like 2d shadows i can't do it using just clip children
what i need is the shadows as mask like in 3.x

did you see the effect in among us when you can't see player behind the wall
you can do this effect in godot 3 using mask light2D

This kind of culling should be done server-side to prevent cheats from revealing player positions.

what is the harm of bring back this blend mode?

@arabgamedev I also miss this feature, because I wanted to the same thing. To get the same effect you can write a shader to calculate the shadows with the new SDF functions and make the texture transparent in the shadow. These are the resources I used:

@arabgamedev Я тоже скучаю по этой функции, потому что я хотел того же самого. Чтобы получить тот же эффект, вы можете написать шейдер для вычисления теней с помощью новых функций SDF и сделать текстуру прозрачной в тени. Это те ресурсы, которые я использовал:

Hi. I am another person with this problem. Can you please post how you worked it out here?
