Hi,
I'm trying to use good old T4M shader in Unity 5 and it seems there is an extra interpolator in action.
Is there a way to still use it without setting it to shader target 4.0?
Shader "T4MShaders/ShaderModel2/Diffuse/T4M 4 Textures" {
Properties {
_Splat0 ("Layer 1", 2D) = "white" {}
_Splat1 ("Layer 2", 2D) = "white" {}
_Splat2 ("Layer 3", 2D) = "white" {}
_Splat3 ("Layer 4", 2D) = "white" {}
_Control ("Control (RGBA)", 2D) = "white" {}
_MainTex ("Never Used", 2D) = "white" {}
}
SubShader {
Tags {
"SplatCount" = "4"
"RenderType" = "Opaque"
}

fixed4 splat_control = tex2D (_Control, IN.uv_Control).rgba;
fixed3 lay1 = tex2D (_Splat0, IN.uv_Splat0);
fixed3 lay1_2 = tex2D (_Splat0, IN.uv_Splat0 * -0.015);
fixed3 lay2 = tex2D (_Splat1, IN.uv_Splat1);
fixed3 lay2_2 = tex2D (_Splat1, IN.uv_Splat1 * -0.015);

fixed3 lay4_2 = tex2D (_Splat3, IN.uv_Splat3 * -0.015);
o.Alpha = 0.0;
o.Albedo.rgb = (((lay1 * splat_control.r / 2) + (lay1_2 * splat_control.r / 2)) +
