Problem with Stencil shader and order
Object A and C use same shader (FOVAvailable).
Object B use FOVNotAvailable shader.
My goal is to make overlapped regions between A and B cut off only if A is below B.
Object C is above object B so i don't want overlapped regions between them cut off
What should i change in the shaders? Thanks in advance.
FOVAvailable shader :
Shader "Shader Forge/FOVAvailable" {
Properties {
_Color ("Color", Color) = (0,0.6229718,0.9926471,1)
_Transparent ("Transparent", Float ) = 0.4
[HideInInspector]_Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
}
SubShader {
Tags {
"IgnoreProjector"="True"
"Queue"="Transparent"
