Hi,
Im trying to make a custom shader to have a material stretch across multiple objects of different shapes (walls with holes voor doors, windows and normal walls)
I almost fixed it but the material is rotated 90 degrees now if I look at it from 1 side:
What am I missing? This is the shader:
Shader "WallShader" {
Properties {
_Color ("Main Color", Color) = (1,1,1,1)
_MainTex ("Base (RGB)", 2D) = "white" {}
_Scale("Texture Scale", Float) = 1.0
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 200
CGPROGRAM
#pragma surface surf Lambert
sampler2D _MainTex;
fixed4 _Color;
float _Scale;
struct Input {
float3 worldNormal;
float3 worldPos;
};
void surf (Input IN, inout SurfaceOutput o) {
float2 UV;
fixed4 c;
if (abs(IN.worldNormal.x) > 0.5) {
UV = IN.worldPos.yz; // side
c = tex2D(_MainTex, UV* _Scale); // use WALL texture
}
else if (abs(IN.worldNormal.z) > 0.5) {
UV = IN.worldPos.xy; // front
c = tex2D(_MainTex, UV* _Scale); // use WALL texture
}
else if (abs(IN.worldNormal.y) > 0.5) {
UV = IN.worldPos.xz; // back
c = tex2D(_MainTex, UV* _Scale); // use WALL texture
}
else {
UV = IN.worldPos.xz; // top
c = tex2D(_MainTex, UV* _Scale); // use FLR texture
}
o.Albedo = c.rgb * _Color;
}
ENDCG
