Shader "Hidden/UI Default (Soft Masked)"
{
    // This is a shader that replaces the Unity's Default UI shader. It has all capabilities
    // of the Default UI and also supports Soft Mask. It is a bit complicated because it
    // reflects changes of the Default UI shader between Unity versions. If you're searching
    // for an example of how to add Soft Mask support, you may check CustomWithSoftMask.shader
    // that's included in the package.
