Can't move texture by modify 'offset' in inspector
I want to do some UV animation. So I find some ways to do it. eg: renderer.materials[materialIndex].SetTextureOffset(textureName, uvOffset);
Butthere is nothing happened.Then I change the parameter 'offset' in inspector panel by hand--nothing happen too.
So I just wonder if my shader does NOT support change Texture's UVs.There aer codes of my shader:
Shader "Custom/AlphaMask" {
Properties
{
_Color ("Main Color", Color) = (1,1,1,1)
_MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
_MaskTex ("Mask (A)", 2D) = "white" {}
_Cutoff ("Cutoff", Range(0,1)) = 0.5
}

#pragma vertex vert
#pragma fragment frag
sampler2D _MainTex;
sampler2D _MaskTex;
fixed4 _Color;
float _Cutoff;
struct appdata
{
float4 vertex : POSITION;
float4 texcoord : TEXCOORD0;
};
struct v2f
{
float4 pos : SV_POSITION;
float2 uv : TEXCOORD0;
};
v2f vert (appdata v)
{
v2f o;
o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
o.uv = v.texcoord.xy;
return o;
}
half4 frag(v2f i) : COLOR
{
fixed4 c = _Color * tex2D(_MainTex, i.uv);
fixed ca = tex2D(_MaskTex, i.uv).a;
c.a *= ca >= _Cutoff ? 0f : 1f;
return c;
}
ENDCG
}
}
SubShader
{
AlphaTest LEqual [_Cutoff]
Pass
{
SetTexture [_MaskTex] {combine texture}
SetTexture [_MainTex] {combine texture, previous}
}
}
}
Fallback "Transparent/VertexLit"
}
This problem is really driving me crary. It will be nice if somebody help.Thanks!

@mckelynn This shader doesn't support it. To add support for uv offset and scaling, include UnityCG.cginc, add the uniform
float4 _$$anonymous$$ainTex_ST;below
sampler2D _$$anonymous$$ainTex;and change the line
o.uv = v.texcoord.xy;to
o.uv = TRANSFOR$$anonymous$$_TEX(v.texcoord.xy, _$$anonymous$$ainTex);
