parallax in editor but not in standalone

Unity Engine
1

The following stripped-down parallax shader works in the Unity editor game view, but not in a UB standalone build (it is black). Is there something I can change to get it working in standalone builds?

Shader "SimpleParallax" 
{
	Properties
	{
		_Parallax ("Height", Range (0.005, .1)) = 0.02
		_MainTex ("Base (RGB)", 2D) = "white" {}
		_BumpMap ("Bumpmap (RGB) Height (A)", 2D) = "bump" {}
	}

	SubShader
	{
		Pass
		{
			CGPROGRAM
			// profiles arbfp1
			// fragment frag
			// vertex vert

			#include "UnityCG.cginc"

			struct v2f
			{
				float4  pos         : POSITION;
				float2	uv			: TEXCOORD0;
				float3	viewDirT	: TEXCOORD1;
			}; 
			struct v2f2
			{
				float2	uv			: TEXCOORD0;
				float3	viewDirT	: TEXCOORD1;
			};

			v2f vert (appdata_tan v)
			{
				v2f o;
				o.pos = mul( glstate.matrix.mvp, v.vertex );
				o.uv = TRANSFORM_UV(1);

				TANGENT_SPACE_ROTATION;
				o.viewDirT = mul( rotation, ObjSpaceViewDir( v.vertex ) );

				return o;
			}


			uniform sampler2D _BumpMap : register(s0);
			uniform sampler2D _MainTex : register(s1);
			uniform float _Parallax;

			float4 frag (v2f2 i)  : COLOR
			{
				half h = tex2D( _BumpMap, i.uv ).w;
				float2 offset = ParallaxOffset( h, _Parallax, i.viewDirT );
				i.uv += offset;
				float4 texcol = tex2D(_MainTex,i.uv);

				return texcol;
			}
			ENDCG
		}
	}
}

I am using a MacMini with Intel GMA 950 graphics.

Thank you.

One obvious thing that is missing is:

SetTexture[_BumpMap] {}
SetTexture[_MainTex] {}

Just after ENDCG. In Unity 1.x those dummy SetTexture commands are required for the textures to be set up correctly. In the editor it probably just happens that the textures are set up by something else.

That fixed it–thanks Aras!
