Hi, I want to apply 2D light effects to my 2D game so it could have day/night time. my game is a zombie shooting genre with main character on the left side of the screen, who will fight hordes of zombies coming from the right side of the screen. I divide the scene into "lanes" and the zombies will spawn on these lanes. when I tried to apply 2D light to the game, I ran into a problem, a light from a lane will affect sprite which it wasn't supposed to affect. please check this image: - the light affects the zombie A => this is expected - the light also affects zombie B => this is the problem, the light should not affect zombie B. zombie A and B have different sorting order value. The light can affect specific sorting layers but I don't see any option to make it affect specific sorting range (example: affect range: from -100 to 100, then sprite in sorting order 150 will not be affected) after searching around, I stumbled upon this post which has this result: I think this is what I want. the solution involves modifying a shader and I don't know anything about shader can anyone point me a direction to solve this? if modifying the shader is too hard, can I modify the 2D light script to add a range of "target sorting layers" ? Thank you for reading, Tom.
