In our project we have to change the stencil value.
As the scrollview’s viewport uses the stencil to mask the content, we used to replace the UI/Default shader in this component with a custom one.
We recently upgraded to Unity 2021.1.3.1f1 but it doesn’t seem to work anymore.
I downloaded the default builtin shaders for this version, but even if I replace the viewport material with one that uses the code for the UI/Default shader, nothing appears in my scroll view.
Update: Nevermind. I didn’t use the right shader for the content
