Avoid multiply alpha

Hi there,

In my game i manage shadows for my characters and weapons (with Sprites-Default shader), but when they are overlapping, the color is darker : . I don't know if it is possible, but i would like to avoid alpha multiply on my sprites, in order to get only 1 "black" color for my shadows, that is to say get this : .

I'm quite noob about shaders, i tried to modify blending mode but nothing get me what i need =(

If someone can help me that would be great =)

 

This issue has shown up in hundreds of threads and its mainly because this is natural hardware behavior and is not obviously overcome. You can do it by e.g. rendering shadows to the alpha channel of the screen and then later using a different shader to cover the screen using a color that combines with the alpha channel. But there are other ways.

 

Thank you for the answer, i'll look for this "alpha channel of the screen", never heard about it.

Btw i found half of a solution there : https://mispy.me/unity-alpha-blending-overlap/
But it doesn't work if i check "Flip X" or "Flip Y" on the sprite renderer (it works if i check both)
