Texture tiling not working for some shader

Tiling is not working in Standard Assets Water (Basic) shader "FX/Water (simple)".
when i change the tiling value, nothing happens. but when I switch to other shader such as diffuse, tiling starts working again.

I tried to simplify the shader to this, but tiling still doesn't work:
Shader"FX/Water (simple)" {
Properties {
_MainTex ("Fallbacktexture", 2D) = "" { }
}
//singletexture
Subshader {
Tags { "RenderType"="Opaque" }
Pass {
Color (0.5,0.5,0.5,0)
SetTexture [_MainTex] {
Matrix [_WaveMatrix]
combinetexture, primary
}
}
}

}
}
}


am i missing anything?

 

Well, the _MainTex texture is using the _WaveMatrix matrix for the tiling, so the tiling values of the _MainTex texture are not used. With a shader that is not fixed pipeline, it would be easy to combine both tiling matrices. It might even fit in a fixed pipeline shader.

 

Thanks! I found that TRANSFORM_TEX solves the problem!
