No Shadows On Custom Shader

Hello I've got a problem receiving shadows on my custom shader. I've got a mesh with 2 Materials:

The road material is a built in diffuse shader. And there (as you may see) I can receive shadows.

The second material is a really simple custom shader, ant there I cannot see any shadow.

I've tried several shaders, and no one cast any shader (except for the built in shaders).

Any help would be apreciated. Thank you!

PD: I'm using unity free

Here's my simple custom shader.

Shader "Blend 2 Textures" {

Properties {

_MainTex ("Texture 1", 2D) = "" ​

}

SubShader {

Lighting On
Pass {

SetTexture[_MainTex]​

}​

}
Fallback "Diffuse"​

}
