Trouble with custom structs...

Unity Engine
1

Okay, I’m having a bad time with structs…

well the problem is that my vert program is not accepting my custom struct outside “Pass{}”

for example i have these structs:

		struct INPUT {
		    float4 vertex : POSITION;
		    float3 normal : NORMAL;
		    float3 texcoord : TEXCOORD0;
		    float4 tangent : TANGENT;
		};
		
		struct OUTPUT {
		    float4 position : SV_POSITION;
		    float4 color : COLOR;
		};

and this is my vert function:

		OUTPUT VertexShader (INPUT input) {
		    OUTPUT output;
		    output.position = mul( UNITY_MATRIX_MVP, input.vertex);
		    output.color.xyz = binormal * 0.5 + 0.5;
		    output.color.w = 1.0;
		    output.vertex.xyz += input.normal * _Amount;
		    return output;
		}

And i get this error:

so as i can see it forces me to use UnityCG.cginc’s default struct… but why??? I dont want to use it! I want to use my own structs :frowning:

Looks like you’re using a surface shader, which requires that you use appdata_full. Custom ones are for vert/frag shaders only.

If you want to modify the values of that, check out the example in the docs, about 3/4 of the way down this page (“Normal Extrusion with Vertex Modifier”);
