Hi all, I'm working on a tower defense where all of my enemies are on a simple 4 vertex plane with transparent material. I'm using the Mobile/Transparent/VertexLit shader right now, but mostly any transparent shader which Unity has makes FPS drop when multiple enemies are on top of each other which I believe makes redrawing? Is there any way to force to not render something if it is on top of another object? Or is there any way to improve performance for transparent overlapping planes?
