Hi, I want to use “screen blending” from photoshop in my Unity 2D game, I want to use that for exported lights from 3D Max that we want to use in our game, Now for a sample, I have my sprite that I want to mask it :

And I also have a mask for it :

Now my question is how to make this in Unity like this :

I’ve searched a lot and I find out it can be done with shaders, but I have no idea how it works.
Can make this happen by Sprite mask?
