Shader Programming, Volume 5
Sebastian Monroy

Couldn’t solve the problem of “Too many texture interpolators…” but you can comment out one of the input textures and its associated uv for the sake of seeing some results on the screen.
e.g. remove the lines:
_ATexture (“Alpha Channel Texture”, 2D) = “”{}

sampler2D _ATexture;

float2 uv_ATexture;

float4 aTexData = tex2D(_ATexture, IN.uv_ATexture);

finalColor = lerp(finalColor, aTexData,blendData.a);
