Rendering TextBlock implement text gradient


I have learn some basic knowledge about xenko from the sample.I have add UI in my scene and I implement a script to change the overall color of the text in TextBlock.
How can I use a render to implement TextBlock text gradient like tthis?


Currently it is not possible as shader can’t be applied to UI elements.
That is something we would like to be able to do but it requires a new way of rendering the UI (or a new UI api/implementation).
