    Hello,
    BaseVertexEffect had a virtual method that gets a list of UIVertex
    which i used to add vertices and reorder the existing ones...
    Now I get a mesh and tried to add vertices and colors but it just causes the text to disappear
    I have also tried adding indices but it doesnt work either..
    And I cannot go back to BaseVertexEffect because it is forcing me to use BaseMeshEffect by an error.

    The code i used to have in 5.0: http://pastebin.com/9Z1D130h

    Hi,
    I had your same issue. To solved it, I just followed the same approach the new Shadow effect does.

    Code (csharp):
    1.  
    2.     #if UNITY_5_2
    3.     public partial class MyEffect : BaseMeshEffect
    4.     #else
    5.     public partial class MyEffect : BaseVertexEffect
    6.     #endif
    7.     {
    8.         #if UNITY_5_2
    9.         public override void ModifyMesh (Mesh mesh)
    10.         {
    11.             if (!this.IsActive())
    12.                 return;
    13.  
    14.             List<UIVertex> list = new List<UIVertex>();
    15.             using (VertexHelper vertexHelper = new VertexHelper(mesh))
    16.             {
    17.                 vertexHelper.GetUIVertexStream(list);
    18.             }
    19.  
    20.             ModifyVertices(list);  // calls the old ModifyVertices which was used on pre 5.2
    21.  
    22.             using (VertexHelper vertexHelper2 = new VertexHelper())
    23.             {
    24.                 vertexHelper2.AddUIVertexTriangleStream(list);
    25.                 vertexHelper2.FillMesh(mesh);
    26.             }
    27.         }
    28.         #endif
    29.  
    30.         public void ModifyVertices(List<UIVertex> verts)
    31.         {
    32.                 // you code goes here
    33.         }
    34.  

    Notice that my declaration uses BaseMeshEffect when 5.2 and BaseVertexEffect otherwise.

    Also notice, that the list vertices now has triangles instead of quads.

    Thanks for the example fpuig. Is this UI source for 5.2 beta available yet thought? The latest update I see on the Bitbucket repo is from April...

    Edit: Decompiling seems to be good enough for now.
