UGUI Unity5.6 CanvasRenderer vertex define has no uv1 ???

Unity Engine
1

I used UI vertex extra parameters , just uv1 , so I used both uv0 and uv1 . Using the api
" VertexHelper.AddVert(Vector3 position, Color32 color, Vector2 uv0, Vector2 uv1, Vector3 normal, Vector4 tangent);" . and my shader use VSInput texcoord1 like this

struct appdata_t
{
float4 vertex : POSITION;
float4 color : COLOR;
float2 texcoord : TEXCOORD0;
float2 texcoord1: TEXCOORD1;
};

My code works well in 5.4 and all lower Unity version . But failed on 5.6 and unity 2017. So I think uv1 is not supported any more in CanvasRenderer. This really bothers me. Can any one help me ? Thanks a lot .

And happenly I found a similar question, but I only wanna to use TEXCOORD1 …https://forum.unity3d.com/threads/ui-batching-and-extra-parameters.338661/

Could this be connected to the new settings in the canvas? You can set them in Additional Shader Channels in the canvas component:
