Shadows in a shader with vertex modifier
How can i have correct shadows in an mesh with vertices deslocated by the shader? The shadows appear like the mesh wasn't changed.
I'm using this shader:
Shader "Example/Normal Extrusion" {
Properties {
_MainTex ("Texture", 2D) = "white" {}
_Amount ("Extrusion Amount", Range(-1,1)) = 0.5
}
SubShader {
Tags { "RenderType" = "Opaque" }
CGPROGRAM
#pragma surface surf Lambert vertex:vert
struct Input {
float2 uv_MainTex;
};
float _Amount;
void vert (inout appdata_full v) {
v.vertex.xyz += v.normal * _Amount;
}
sampler2D _MainTex;
void surf (Input IN, inout SurfaceOutput o) {
o.Albedo = tex2D (_MainTex, IN.uv_MainTex).rgb;
}
ENDCG
}
Fallback "Diffuse"
}
found here https://docs.unity3d.com/Manual/SL-SurfaceShaderExamples.html.
You have to add the 'addshadow' keyword to the surface declaration, i.e.
#pragma surface surf Lambert vertex:vert addshadow
thanks, this works, but when try to move only some vertices, using: if(v.vertex.y>0.5f) v.vertex.xyz += v.normal * _Amount;
it doesn't work, what i'm really trying to do is to deform just some vertices, what can i do?
Which doesn't work, the shadows or the vertex displacement?
the shadows, the vertex deforms but the shadows stay the same
I know this is from two years ago but thank you very much
